GTA san andreas where you get on the motorcycle and jump over hoover dam. That was so much fun. Another one that gets an honorable mention is infamous. You are a mutant that collects electricity form any electrical source. You store it in your body, then you go fight the bad guys by expelling the electricity on them. Fun game.
It really is. I dare anyone to try not to laugh at this game's shenanigans while they're baked as a cake. XD
the BEST thing to do when you're stoned on a nice energetic sativa strain is do all the grinding for your Final Fantasy type games or any game where you need to do major levelling up. There's a part in FFXIII where you're in a giant field with a shit ton of fightable animals and I ground for like five straight hours and massively levelled up to a point where the game wasn't even fun anymore it was just easy. For a more relaxed high though, I love simple games like Animal Crossing/Harvest Moon cause they're so laid back and the soundtracks are usually awesome. Running around in Skyrim is also a good choice just to chill out and have a good time.
Zoning out to Animal Crossing New Leaf on my 3DS lol. I can't wait for the new game, Happy Home Designer to come out.
