The pay to play content is from $1-$3 (although there is one bundle of 3 for more). If has items such as more dungeons so your characters can level up higher, increase building caps, different costumes for a couple of the characters, different buildings for stronger units, etc.
Is this the game Actraiser? (not familiar with it)

Anyways, this is nothing like that.
I would put it closer to MySims.
