Just play the original if you haven't. It's pretty good. The remake is... okay. Just not really something that needed to be remade. It has some aspects that are better, some that are worse.
Ohhhh, I never read dev promises for future updates. As long as they release regularly and don't go radio silent, I'm cool. To me that doesn't sound like scamming tho, more like over-promising and under-delivering. Is he charging patrons extra for these features that end up not being in his updates?
