Back in the day, Resident Evil 4 and GTA San Andreas were my favourite games to play high.
Before those games came out, it was stuff like Super Mario Sunshine, Metroid Prime, THPS3&4, the old N64 wrestling games like No Mercy, Revenge etc...
In the last few years, I remember Bioshock (1&2) being particularly awesome to play while in that state, especially with headphones (hearing splicers say all sorts of crazy shit from afar is pretty freaky while stoned). Bioshock Infinite's DLC was also awesome to play through while high.
I have a feeling Dishonored would be a great game to play while high but I haven't done so (to the extent I'd like) yet.
I love survival horror games and have often tried to play particularly dark/messed up ones while stoned. Since weed intensifies everything for me, the environment in those types of games always seems so much more fucked up and 'evil', simple things like the textures on walls and doors will stand out way more as being inherently creepy/dark.
I remember doing some form of weed edible about 5 years ago and then trying to play the start section of Silent Hill 3 (the lakeside amusement park nightmare) in the stage that the high was coming on. It was pretty unpleasant as I was too fucked up to know what to do so I would just run around getting corned by those big 'closer' enemies all the time. The audio was just so fucking twisted it really made for quite a bad experience, so I just turned it off after presumably 3-5 minutes of being stuck and not being able to get away. I remember playing that game other times while stoned and enjoying it a bit more but it always feels extremely creepy, especially in the otherworld.
Silent Hill 2 is one I've played more extensively while high and it's much less mentally draining than SH3 and things like running through the foggy town feels awesome and super immersive in that mindstate. Areas like the prison, labyrinth etc are on par with a lot of the SH3 areas in terms of that feeling of "eww everything's so fucked up". Playing the opening of SH2 (basically from the start till you reach the apartments) while stoned and wearing headphones is insane, some of the things you hear in the distance... The original Silent Hill is in some ways still the scariest to me, playing through the whole Midwich elementary section including the otherworld transformation is quite the challenge while under the influence.
I remember loading PT one time about 6 months ago, being pretty high at the time and literally taking a few in-game steps then saying fuck it and quitting out of fear, scaredness, and last but not least, being afraid.
Condemned is another game that was similarly horrifying to play high, especially the department store (not only the mannequins, but the old christmas decorations and background music etc was creepy as fuck) and the school level.
I subject myself to similarly dark films while stoned sometimes too, like I've watched Suspiria and Session 9 (two of my fav horror movies) while stoned several times, and they're both extremely chilling/disturbing, sound design being a huge part of that.
On the more fun side of things, Mortal Kombat (9) was good fun while stoned, Hitman Blood Money (and Contracts), Hotline Miami 1&2. Heaps of others, most games are enhanced by weed really...
I almost never play video games after drinking as alcohol severely decreases my attention span so I can't focus properly - good thing I don't drink that often.
