Honestly kind of an iffy game. I mean it has a lot of potential since you can not only collect cards, but upgrade them as well. So this leads to more and more abilities and options as you go. But the game also often leads to a point where you've gotta grind to make progress because you need to upgrade your cards and/or get others which requires a bunch of repeat trips through the same opponents. Like you'll probably be able to get by fine on the regular trainers, but when you hit a gym leader's more upgraded cards, you get overwhelmed as there's not much you can do other than tell it you aren't ready and do another loop. Then repeat as needed.
