Profanity: Two Worlds Epic Edition - ultimate bleh. Such a big world and I don't want to see any of it.
I've seen it all 3+ times. Don't really even need a map anymore. It is very polarizing.
For me Haegemonia maybe. I didn't play much of it. It looks cool but I don't think it was really what I was expecting. I'm not convinced I understand it well enough to speak illy of it, but I am sure my interest was not seize by it upon my first tasting.
Then there is Space Rangers 2 which is only the horrible GOG tragedy it is because NOBODY CAN BUY IT it anymore. So any of you poor bastards that don't own it won't, and that should be a good reason to feel some regret.
