>>42517309Instead of the PP system from Pokemon it has a stamina system. You get a little stamina back each turn, and have a "Rest" option in battle to restore some stamina. So you'll never run out of PP. You also start with full stamina each battle. So as long as your HP is holding up you can avoid going back to town to heal, which is nice.
It's also more difficult than Pokemon in general, which is nice. There's some actual challenge.
The downsides are mostly due to it being early access. So there's only 3 of the "Gyms" in the game and there's no "end game" really. It's quite buggy, but that's being taken care of quite quickly. There's a lot to still be added, but the game is currently set to have a full release next year, so hopefully it won't take a super long time to be a feature complete game.
