I've got a list. Not necessarily games I outright hate (though some are), but more games I have issues with.
Metroid for the NES: Find out how Samus is getting to those checkpoints on Zebes. It must be some kind of teleporter. Once I've found the teleporter, I'll hack it so that Samus starts off each life with a full stock of health that she can carry. That way, she won't have to choose between death or grinding for 20 minutes to pick up enough health to survive Brinstar Depths or Norfair.
Scooby-Doo (SNES): Phone the police to pick up the jokers in masks. And maybe throw Scooby a tree branch so that the sandwiches in the sandwich-stacking minigame don't fall apart.
Metroid Other M: At the very least, I'd probably try to get Samus to start a conversation with Adam. I just don't buy this relationship. And I'd probably try to goad Samus into using her Super Missiles on the first Super Missile door we see because that's where the "plot" of the game is. I'll leave it at that, though.
Sigma Star Saga (GBA): The alien race you're fighting is called the Krill, IIRC. If that's the case, I'd try to call in a space whale to eat them all. Or maybe I'd fight off the enemies above in my comfy Vic Viper knockoff while your hero is left to slowly crawl through the "underworld".
Pokemon Red (GB): I am a big Pokemon fan, but I have issues with the original games looking back on them. If I was trapped in it, I'd figure out the greatest mystery of the region: why is it perpetually daytime in Kanto? I bet it's all part of the Psychic conspiracy that ruled the game with an iron third-eye. Sabrina knows that just to the west of Saffron City, there are Dark-type Pokemon that can scare and defeat her easily, but nobody's ever going to use them against her because you can only get those ones (at least in Kanto) at night. And because the sun never sets here, nobody's ever going to catch and Houndour or Murkrow to screw Sabrina up easily. Red can brag all he wants about stopping Team Rocket (though I doubt he will; he's a quiet one), and Blue can brag about being the League Champion before Red was. Those guys will have nothing on the dude who brought the effing moon back to the Pokemon world.
