Lucumo: Battle for Wesnoth is still relevant? Nice. I played that game with my friends back in 2006.
Can't really help you with much as I've played more SRPGs on consoles than PC. And since you don't really care about anime, most of the PC stuff like Farland Symphony and consoles like Super Robot Taisen aren't relevant. Heck, basically all Japanese SRPGs/TRPGs are anime: Fire Emblem (the new entries suck though), the ...Wars series, Disgaea series, Front Mission series, Shining series, Phantom Brave etc etc.
I would go with something like King's Bounty, as was mentioned by Cavalary. Legend of Eisenwald I have actually played and I don't think it's a good game. It was some major issues which makes it "ok". Apart from that, maybe try something like the Banner Saga or the Shadowrun games? Haven't played any of those though.
Given the sales on here, DIABLO is still relevant and that was a game I enjoyed on my mom's computer back in 1996.
