Divinity Original Sin and Wasteland 2
Both brilliant RPGs. Both tactical turn based combat, one fantasy, one post apocalyptic (guess which is which).
Ultra short version: wasteland 2 is rather fallout-like (apparently fallout was the 'spiritual successor' to wasteland). Bleak, black humour, and the main thing that stood out for me is your decisions really do change the game. None of this just-changing-the-guards -dialogue crap. Whole areas of the map end up destroyed, and dead is dead for any party member.
Original sin is, now bear with me, a bit of cross between Oblivion with more humour and Deus Ex. The environment and feel is the oblivion with more humour, deus ex is my first point of comparison for a game that lets you solve any given problem in lots of different ways.
Highly recommended. If you like a good RPG, these have really stood out for me. Word of warning though: both are pretty hard, neither hold your hand. Not quite old school enough to have to draw your own map as you go, but old school enough that you have to figure out what to do from the dialogue and clues. One mission in wasteland I actually had to type a keyword in conversation with an NPC to get the best outcome. Those were the days...
Anyway, buy em.
Edit: sort of new, as the betas have been available for a long time now, as they were both kickstarter projects. I've held off playing them till release though, which is pretty recent in both cases.

I've been looking forward to Wasteland 2 as I liked the first one and am a massive Fallout fan. Sounds like I should go get it. Now to see if it's available on OSX or whether it have to parallels it.
