Not playing, but I took another look at the progress of War for the Overworld. It almost looks like a game, now. A little too much DK2 influence (vs. mixing DK1 and 2 a bit more maybe) for my tastes re: the likely campaign format, but still looks kinda nice. The one video I watched that showed the available campaign map (probably the 1st, tutorial one) wasn't too impressive, however. Especially the sound. "We burn with the glory of (someone's) favor" over and over and over...lol. Not quite ready to purchase yet...in a few months maybe.
I might like the sandbox and if they have them, skirmish. Probably won't do the MP. Not sure about the "sin" stuff for getting new rooms and spells. Could be good, tho. At least they're trying something a bit different and not a direct clone in that area.
