Reputation and free games probably. Personally it took turning off the grid to sell me; I appreciate throwbacks to old gameplay, but there are overlooked middle ground a between being Wizardry or Skyrim, and that applies to a lot of other subgenres and styles of gameplay. And we've had more than enough grid based dungeon crawlers for that to NEED more.
More than enough grid based dungeon crawlers? Never! [not even close, really, the genre has been dead on pc for far too long and I am so thankful to Grimrock for reviving it.]
From what I was reading it sounds like switching to FF style ATB with the option of queuing up attacks. Whichever, just as long as I can pause it and take my time to think.
EDIT: Actually, how well do the original games play in their mobile forms? I got it on Android via Humble Bundle and unless there's some advantage to buying it off the PlayStore or the Humble version just doesn't have the original trilogy I'm thinking of using that to play them.
I am playing the original right now on PC, and it holds up except, of course the interface is archaic (spell codes, inventory management, etc) but I got (re)used to that quickly and am having a blast [level 30 or so].
So much nostalgia -- from the monk's chants during healing, to even recalling the basics of some of the map layouts. Wild.
While I haven't played the mobile versions, I have to assume the interface is improved, especially for spell casting.
I have played Silversword on an ipad, however (an obvious and clear homage to Bard's Tale down to the interface) and it was very enjoyable... I assume the originals play well at that size too.
I've got Wasteland 2 and Torment, but I won't be backing this one. The combat in W2 is awful, I have no idea why they think I'd want a game from them that's even more focused on it.
The combat in a drpg like Bard's Tale is nothing like the combat in Wasteland.
