Spiderweb Software (
www.spiderwebsoftware.com) is a very well regarded indie - about 10 games, I think mostly turn-based, multi characters RPGs. One great thing about them is that you can download demos for any / all of the games, and the demos tend to allow about 1/3 of the game to be played through.
There's also a Bards Tale remake out there now called Devil Whiskey, and the Angband variants can be a lot of fun.
And, mmm, you might be able to find a nifty text-based SF 4X game called Anacreon. Which, wow! Doing a quick search via Google reveals that after 15 years, it's been rewritten for Windows, with graphics and a GUI and improvements.
Hmm - maybe I have a diVersion from Dominions for a while now.
