I think you'll love the original unenhanced, unpatched, unmodded Baldur's Gate 2 (I assume the same also applies to BG1 and IWD1).

I trust you're watching AGDQ this week? Glitchy games galore :)

I am like you. I like no glitches games, but sometimes a good glitch can be fun.

I was also going to say Morrowind. The only way I can keep alive is my getting my movements to confuse the AI and making them glitch out (usually they pace back and forth instead of actually pursuing me). And then, of course, there are the big goofy glitches.

Alpha protocol had lots of fun glitches. Once I died and the while level was devoid of enemies. That wasn't a fun glitches. But I remember tons of glitchy exploits you could use to bring down the bad guys. Man I loved that game. I should probably playboy (edit: play it - autocorrect!) again.

Early version of Age of Conan. Obviously setting up a private server is likely a large ordeal but it might be worth it. Me and a couple of friends used to find bugs that let us out of the map and stuff, some places when we entered caused huge performance issues, once even broke the server. I remember my favourite that allowed you to fall down the ground of Eiglophian Mountains, making you appear on the other side of the map, funny thing was that it didn't happen immediately and there weren't that many graphical glitches which made the event feel relatively organic and spontaneous.

Man, I miss that game until they turned into a boring WoW clone.

I like glitches that open new paths of the game, allowing you to explore more even if it's very simple or even stupid. I remember one cave in The Witcher 3 you can jump at the end of a blocked cave in and then sort of fall through the ground on the other side revealing an area that is half-done. It's interesting to see what we weird stuff developers leave behind that is not meant to be seen by playing the actual game, intentional or not.

The unpatched (and, now that I think of it, patched) Fallout 2 was Buggy As All Hell™.

Does this qualify as a glitch?

What game is this?

Duke Nukem 3D had a few that allowed some interesting speedruns.

Baldur's Gate 2 had some changes made to the Infinity engine. One of them, made so you can view inventory while paused, but not allowed to change armor, introduced a glitch where any class could use any perishable item. One of the more interesting results was that anyone could use a Summon Familiar scroll and get a familiar. Also, another glitch allowed you to teleport (to the other side of a door for example) if you use Summon Familiar, or an item with similar properties, in a crowded area.

There used to be an third person online shooter called Gunz: the Duel.

There where some substantial glitches leading to players developing an entire play style around it. Developers tryed to fix it, but the style became so popular that they had to leave it in place.

It was called K-Style (k for Korean where it originated) and basically consisted of being able to cancel out movement animations allowing for a rather uniquer play style.

I haven't looked in a while, but there are still some private servers around I would guess.
