10 years eh? Congrats to Obsidian!
My Obsidian moments then (some minor plot spoilers of older Obsidian games follow)
KOTOR2 I absolutely loved this game! This game was full of great ideas and story, but for me the outstanding memory would probably be Kreia (spelling?). I had previously felt that the binary morality system of KOTOR was a bit simplistic and here was someone in the game pointing out the absurdity of the extreme views of both the jedi and the sith. Perhaps she didn't entirely have my interests at heart then? (Full disclosure, I am only now getting around to playing the restoration mod) Neverwinter Nights 2 My initial experience with this was disappointing as it ran like a dog on my machine at the time. And I'm not talking about one of those greyhounds you see at running tracks here. It was an absolute pig (to belabour the animal metaphor some more). However, several years later I had a new machine and gave it another go. I saw that by this time the game was extensively patched too. I loved it this time around. The moment it really 'took' for me was when we landed at the main city and Khelgar and Neeshka starting arguing - I realised then that these companions and me were going to get on just fine! (More disclosure, I have MotB but have not got around to playing it!) Alpha Protocol The archetypal flawed gem, this one. I have to say I liked this one too though. The supporting cast was one of the best I've seen in any game! My main memory here though is that I somehow didn't manage to rescue Mina from the base at the end, so the final cut scene seemed a little downbeat. Mea culpa though. Fallout: New Vegas According to Steam I have put about 100 hours into this! I can't distill this down to a single memory! Dungeon Siege 3 Not a typical Obsidian game, this one. The gameplay and story were a bit bland by Obsidian's standards (imo) but at the same time it was completely bug free in my experience. I'm not as fond of the dungeon crawler type of game as I am of the more strategic rpgs, but I still played it through to completion. I had the wizard / mage character as my sidekick for much of it and I did like some of his lines.
Anyways, all the best in the future to you Obsidian!
