TRYING TO PLAY ULTIMA 8 BUT I KEEP DOING SHIT LIKE ACTIVATING MOLOTOVS IN TREASURE CHESTS AND THE RESULTS ARE PREDICTABLE.
Hopefully there is more Deus Ex to come. And I'm definitely going to have to check out Deus Ex 1 now.
I never actually beat DX1, but apparently its endings work the same way. Still, excellent game. Once you get past Liberty Island. It is seriously one of the worst opening areas in any game.
If you like DX, I would recommend the Ultima Underwold games and Arx Fatalis (which is sort of a lot smoother to play nowadays than UU, but UU has better stories). They have them on GOG I think. The Theif games are also sort of similar, and... I think you can get those anywhere.
And I'd also recommend System Shock 1 while giving a whole list of reasons why I thought 2 sucked*, except I'm p. sure you can't really by SS1 anywhere right now.
* tl;dr version? Lots of little things bugged me, but the main one was the skill system, which was mostly just there to fuck you up. In Deus Ex 1, skills were by and large nice little bonuses. In SS2, if you never take any weapon repair or maintenance levels, have fun using a wrench on everything.
