Star Wars Knights of the Old Republic is better than Mario 64. So is KoTOR 2. But KoTOR1>KoTOR2
It's not.
Watch this be won by the obscurest game nobody has played and hence nobody can dispute.
Anyway, besides the ones already marked in the OP, I have played and dispute all of the following:
Now I wish I had played all Crash Bandicoot games, because considering how much I dislike the first, I would dispute them all in a heartbeat. >_>
My nominations: Most of my favorites are covered in the OP, but off the top of my head:
999
Crypt of the Necrodancer
Desktop Dungeons
Devil May Cry 3
Enter the Gungeon
FTL
Guild Wars 2
Metal Gear Rising: Revengeance
Persona 4 Golden
Smash 4 Wii U
Starbound
Starfox 64
The Wonderful 101
To the Moon
Transformers: Devastation
Ultra Street Fighter IV
Undertale
World of Warcraft
Xenoblade Chronicles (the Wii original one, not X)
All of these are wrong but some of these are REALLY wrong. Like, you have USFIV on there which is a bottom tier Street Fighter game. Third Strike, ST and Alpha 2 are easily better games.
Actually, most of these are pretty lol.
