I was pleasantly surprised by this one. It has a unique storyline and interface that reminds me of old console RPGs. There are no ads or IAPs. You can upgrade acquired stat cards by rerolling them using earned in-game currency. There is no need or even option that I can see to spend real-world cash. Some reviewers have mentioned game crashes but I havent encountered that at all (maybe because I began with a later version).
