The feathers on their back make a face.

And why shouldn't they?

Ah, that good ol' MS-DOS feel. The original Commander Keen series had 7 entries in total. Though I only played and finished Episode IV, it still left a big impact. And not just on me, on the video game industry in general. This entry featured an enemy called the Dopefish. It was sort of a meme before memes were even a thing. It was so famous among video game devs back then that it received cameos and mentions in other non-related games (in Jazz Jackrabbit 2 for example, there's a sign that reads "Spaz ate the Dopefish").
As for the game itself, it was pretty challenging. Though the enemies were pretty cartoony, they all killed you in one hit. And though you had a weapon (Neural Stunner) some enemies were immune to it. At least you could jump really high.
A mobile game came out recently featuring Keen's kids. But most fans feel it doesn't really do the OG justice...

And on the 69th day, the All-Memey said @letthemhavememes. And he saw that it was unoriginal, but still good.

Thanksgiving pardon? Yeah, you better hope they'll grant you one.

Yeah, it's Friday the 13th. But really, @who_cares? (Well, @jasonmon might)

@xvarnah, I think this covers all your requests. But if you have any more, don't hesitate to tell me.

"Ruh-roh, rit's a rooky rost in Rovember, Rhaggy!"
"Like zoinks, Scoob, can't they just let the ghosts and goblins go, man?"

If you grew up between the 60's and, well, today it's almost impossible that Scooby-Doo in some form or another wasn't part of your childhood.
The incarnations I'm most familiar with were the original seasons from the 60's and 70's, the New Scooby-Doo Movies (I didn't recognize any of the guest stars at the time, but they were still fun), the one with Scrappy Doo, the Boo Brothers and Ghoul School movies, A Pup Named Scooby-Doo, and Scooby-Doo on Zombie Island.
The latter is considered one of the best in the franchise, and I definitely agree. The animation, the songs, the action, and even the scares were all upped in this one. I remember it was one of the few cartoons/movies that actually scared me as a kid.
Also gotta give props that (most of the time) the source of the mysteries the gang solved weren't supernatural, but man-made...

Another pretty obscure title, but nonetheless one of my all-time favorites. When it first came out in 1994, it made a pretty big splash due to its rocking soundtrack, fast-paced gameplay and shareware marketing. It even won game of the year in 1995. It also had a Christmas expansion and a lost episode kind of expansion. I remember the final boss (a giant gray Jazz clone) really creeping me out. And the final boss of the lost levels was Zoonik (guess who they were parodying there).
Its sequel, Jazz Jackrabbit 2, featured a new character (Jazz' brother Spaz) more move, more weapons and more items in general. It also had a Christmas and lost levels expansion (which featured a third playable character: Lori).
Nowadays Jazz 1 is abandonware, but that just means you can get it for free. Jazz 2 online multiplayer servers are actually still running even today...

Don't worry, @famousone's Snarl is worse than his Bite. (But not worse than his Flamethrower)

@xvarnah, finally got a Growlithe. Woof!

(For extra fun, have @mr_pigeonwizard translate the title)

They must have been in the closet.

So I played this game for about 2 years during The Burning Crusade days. My main was a Draenei Shaman on Alliance, and a Blood Elf Paladin on Horde.
It's strange that with all this game had to offer and with how complex it was, my best experience from it was simply travelling in Ghost Wolf form from the Wetlands to Dun Morogh while the sun was setting. Another similar adventure was swimming to the edge of the world (back when fatigue wasn't a thing).
Yes, I also played Hearthstone from 2013 to 2016. And I was around for the Undertaker and Grim Patron metas. Truly wild times (now literally only Wild times).
I still check in on both games every now and then out of curiosity, especially when there's a new expansion.

The coming of the @savage_demmigod shall be heralded by raging skies and twisting lands, and all those who bear witness to this terrible sight shall know the true meaning of eternal torment.

I'm sure this post won't upset anyone, nor will trigger any form of PTSD. People do like to point out the more toxic elements of this show's fandom. But that aside, this was a pretty good series and really it was the fans that made it so enjoyable.
The sheer amount of fan labor (fanfics, fan art, fanimations) this show had was astounding. I don't think I've something like that since the Machinima days of WoW. "My Little Dashie" is perhaps the most well-known of the written fics. While the fan-produced episode "Double Rainboom" is also up there.
The show itself was colorful, fun and it strove to teach important lessons. It also had some pretty big names behind it (like Tara Strong, Q himself John DeLancie and even Weird Al).
Also, I'm aware that it ended a little over a year ago, put it premiered a little over 10 years ago (on 10/10/10). And really the first two seasons is when it had its greatest impact.

When the Karen isn't the one being a Karen.

Yes, "boll" does mean "ball" in Swedish. But @karlboll isn't made of steel, he's flesh and blood (I assume). Does that mean he's a... Swedish meatball? (Again, just speculation on my part)

Don't you mean Jonald Triden?

Okie dokie,
Mamma mia,
@itsamemaria.

Or Kapitan Pazur in Polish (I don't know why I know that). A rather obscure title, but one of my all-time favorites. I can't count how many times I've played it. Partially because it was fun, and partially because it was pretty challenging and unforgiving. You can't have more than 10 lives, there are no continues, and you can't save unless you make it to a designated save point. No to mention that there are instant death traps all over each level. The bosses are no joke either. The first two are okay, though they might take newcomers by surprise. But the third quite literally upercuts the difficulty curve. There is a trick to beat him, but if don't know it, you'll have a hard time.
Aside from its steep difficulty, the game features beautiful graphics that I'd say hold up even by today's standards, including detailed sprites and animations. And naturally, there's the soundtrack which sounds epic. I really wish they made a sequel...

I was looking downward, so I did see the dinosaur first.
