I'll start. NSMB Wii. It was made in 2009 and I've been playing it since 2012, still not tired of it. I find it extremely addictive. (i'm aware it didn't flop, people have heard of it, but I wish it blew up like how MKWii did)
BeamNG.Drive. I wish this game was more popular. The graphics are amazing and it's overall a very fun game to play.
Yakuza 0. Nobody seems to talk about it much, but that game is absolutely great. Unless you don't like seeing someone kick gangsters in the face while break dancing.
Burnout 2. Everyone knows about Burnout 3. B2 cemented things like crash mode. It also had pursuits, real time trials, unique championships, and some of the best original music I've ever heard in a video game.
No, its because it is honestly boring once you've played around with for a bit. There is not much to it.
Marble Marcher. Sure, it's relatively short and you'll need a powerful computer to run some of the higher resolutions, but it is really nice.
The Crash Time series. I played the 4 and it's quite fun, especially in the chases when you can spin the opponent to stop him (boring!), shoot at his car (it's not a GTA game) or smash it to bits (yay!) Someone: you can't smash into traffic to explode it it's not burnout! Me: haha traffic cars go boom
Mobile games are acceptable to post, right? If so, #DRIVE is truly underappreciated. It's probably the best endless runner diving game on the app stores.
