So far this game is very F2P friendly I play a few gacha games here and there, mainly Dokkan and Legends (which is becoming disappointing). This game seems very friendly to those who don't want to spend money! Increasing energy economy, chips for leveling up, completing battle missions \*and\* story missions, it's great!  


Also for those who want to spend, the prices are pretty decent. Looks like about $13.99 for one multi, which is great compared to a lot of other games where one multi can cost anywhere from $24.99-$40.00+.
