Dogz (GBA, don't judge me I had lots of fun with this when I was young omg)
Pokemon fire red (GBA)
and yeah most of my favs are on GBA or DS but Ruby is forever my fav, My first game ever I always love going back to my cousins house and playing with my old GBA games
The trend seems to be new games so; ACNL, Disney Magical World (Might be Disney, but its for the 3DS so I'm including it), Luigi's Mansion, Mario Party, any Mario games really.
Kirby and the Amazing Mirror (criminally underrated)
Kirby's Return to Dreamland
Kirby's Epic Yarn
Animal Crossing: New Leaf
Super Smash Bros. for 3DS
Pokemon Platinum, Black, and X/Y.
Yoshi's New Island
obvi New Leaf, because I haven't put as much time into any other game ever.
Paper Mario Thousand Year Door is my favorite adventure linear game ever. So funny, all the characters are great, great adventure, variety, great progression... SO GOOD
I haven't played Ocarina of Time, but I really want to and I expect it to live up to the hype
Smash and Mario Party recently have a lot of great memories!
and yeah Pokemon is pretty great. Sapphire/Ruby and Black/White probably being in my favorites
but some of the old spin-offs were great! Pokemon snap and Pokemon Puzzle League! loved both so much! Nintendo needs to get more of these rather than the bogus spinoffs they put off nowadays
