So I recently read that the lead designer on this is actually Julian Gollop, who all the cool kids know created the original X-COM. Sure, this seems like just another one of the seeming-billions of Tom Clancy games at first, but the design pedigree is enough to make this one of my most anticipated 3DS games now. So this is less a "discussion" than a "I can't believe they don't mention that on the product page, because that made the difference between me ignoring the game and pre-ordering it" kind of thing, but there you go.
All in all what I see as very good reviews for the game in Gaming sites, with the main criticisms (when there are) being rather inconsequential in my book. http://www.metacritic.com/game/3ds/tom-clancys-ghost-recon-shadow-wars/critic-reviews . 70 from Eurogamer and IGN, the rest so far (Gamespot, ONM UK, GamesTM, etc) 80.
Yeah i just ordered this with my insanely high amount of credit accrued from 3ds purchase/buying 2 launch games...after watching a gameplay vid and hearing it compared to x-com (and having the resulting minute-long orgasm) i couldn't say no. How I've been oblivious to this game's existence til now I'll never know...but yeah--psyched.
