I don't think I played a single obsidian game. Not even once or out of curiosity. Other than Knights of the Old Republic 2. Nothing against them, but none of the games they have developed hold my interests.For me, I remember a total of....well I guess 3 things, because the Russian lady banging my PC was a fairly unique gaming experience. It's honestly the only time in gaming I can recall a woman sexually (assaulting? I mean I did choose Agree, so I guess not) a protagonist as he's tied up on a table. So that was new I guess.
Other than that, I remember A. The thing with that merc group's owner and how he really liked me because I didn't kill his men, and was sneaky enough to avoid detection. And B. The fact that the game gave you little perks based on your playstyle, that further specialized your playstyle (the "you did a lot of sneaky takedowns, so here's a perk that makes you even harder to detect") That is literally all I remember about that game.
But, I might be a bit biased, as I genuinely don't like Obsidian's titles. Other than Tyranny, which was fun, but was still something of a chore to play through until I got to the part that wasn't me playing the servant of an asshole. Otherwise, I personally think they are highly overrated.
