I have the old Thunderstone and 3 expansions and was looking into buying Thunderstone Advanced. I don't want to mix them so it would be buying TS Adv as a separate game. Are the two versions pretty much the same game or is there enough differences to warrant buying TS Adv?
This is just my personal opinion, but the way that Thunderstone Advance has been balanced takes away a bit of the fun in the original. Popular favorites at my house include swingy stuff like Outlands with a Claymore. I don't think there's enough there to warrant buying Advance if you're enjoying the original stuff.
