Do you know any really complex, innovative and playable computer strategy/RPG games worth playing? When I was a bit younger I used to play quite a lot and I think I've played every major title there is, from Civilization through Heroes of M&M to Planescape:Torment. Now most games seem to be boring (I got older :) ), they hardly ever introduce any genuinely new elements into gameplay, and that's especially true about mass-market games, so I'm looking for some less known titles. As for RPG I tried roguelike stuff like ADOM, but that's just hack'n'slash, and I tried Stars!, but I felt there's more bureaucracy there than real gaming. I'd like to find something really complex and difficult, but Google/Wikipedia bring nothing of that kind. Any suggestions?
