Because I grew up with these types of video games in the 90's I loved this episode. It was fun to look and pin point what games they were borrowing from. I also loved the way they were able to reenact how people play video games in large groups (so like hitting each other on purpose and only jumping around for no real reason (Troy)).
I guess the only videogame based episode i could compaire this one too (well one that I can think of off the top of my head) would be the WOW episode from South Park. I dont know if I can say this ones better or worse because they both used their subject matter in really fun ways and they were using two different types of games.
So if you like Community and if you like retro games then you should give it a watch. And I got to say this, I hope that they release this game someday and that you could play as all the study group members. That would be cool
