Hmm, I'm kind of torn between Mount & Blade II: Bannerlord and Rome 2: Total War, though I'm not so sure my hopes are up about the latter. Could suck hard like Medieval 2 did, and I doubt we'll see a Witcher 3 by the end of the year, so yeah, I'm gonna go with Bannerlord. There is that Wasteland 2 coming up I believe, that looks pretty cool, and Gloria Victis is looking decent, and may well be my very first MMORPG. There's a few upcoming games that interest me.
But for now, Bannerlord definitely. I'm very interested in seeing what TaleWorlds does with it.
