There aren't many games that I like, actually. The Animal Crossing series is pretty much my favourite, mostly because it's very easy and relaxing to play. I tend to get frustrated with games quickly.
But if I were to pick just one, it has got to be Undertale. I like it more for the stories and the characters than I like the gameplay, but that is not to say that I don't enjoy the gameplay.
the last of us is my all time favorite bae. then theres ni no kuni,, mirrors edge,, skyrim and alice madness returns that i love on the ps3. also really like the bioshock stuff but idk if i consider it my favorite. on the wii my favorite stuff is probably the avatar games. for pc i have lot of the assassins creed games those are pretty dope. and on 3ds its obviously acnl and also pokemon x. on the regular ds i love professor layton. and then there was this game i once pirated called hatoful boyfriend. a pigeon dating simulator. best damn simulator ever.
I love a lot of the PC games I've played over the past few years but when I think of another game that I've loyally played over the years, it's pokemon. so, I think it has to be pokemon!
There are so many games I like, but I really love all Pok?mon games. My favorites are SoulSilver and White. I also love Splatoon. Phoenix Wright is another series I really like.
My favorite game will always be Metroid Prime. I played it before I even understood game design and was absolutely blown away, and I'm even more blown away now that I do understand game design and Metroid lore.
Final Fantasy VI and IX, Skies of Arcadia, Tales of Symphonia, Eternal Sonata, Chrono Trigger, Lunar: Silver Star Story, Lunar: Eternal Blue, all Pok?mon games, especially the Mystery Dungeon spin-offs, all Kirby games, Beyond Good and Evil...
