I am fascinated by this. Monster Strike was actually a lot of fun despite being a huge gacha cash grab with garbage rates. The co-op made things exciting and the mechanics were interesting. If this game here delivers that gameplay without the IAP gacha system, I'll be all over it.
Also, in response to my original question Pathfinder and the response by Jarsonot, I have decided to give it a shot. The mechanics are a bit confusing, but I think I'm getting the hang of it. It seems like it could be a lot of fun. The only MAJOR issue I have is that I am completely unsure of what the store offers. There's a whole bunch of crap - gold, scenarios, treasure chests, etc. If I get to the point where I want to buy anything, I know I'll have to lookup the "optimal purchase" to get what I want. That seems like such a shitty solution, but we'll see.
