Christ Centered Gamer

I dont think many of you have heard of this one yet. Battle for Wesnoth is an open source, community driven turn based stratagty game. Its fun and runs on most PCs since it isnt a very demanding game, there is also an unofficial port for Android.
I have been playing this for awhile and recommend it for my fellow RPG addicts

This is one of my favorites. I'd call it closer to a strategy game than an RPG, though.

I think it's more famous on Linux based OS's than Windows. Still, I love it.
