There is a sticky post on top of you where you can ask anything. One that people seem to like a lot here is Puzzle and Dragons, which has sub r / puzzleanddragons, If you need some help. The term gacha is often applied to these types of games and there's bunch of them. It should definitely be on the Play Store, here's a link that should work. There was DBZ collab while back, Batman one, and a bunch of other neat stuff. It also has different collaborations with various other games and stuff. There is player's Choice God Fest coming up soon, that would be the perfect time to start. And with the multiplayer aspect, you can even get carried through lot of dungeons to help you get those drops. You get a lot of free stones from beating dungeons, and there are plenty of farmable units that can compliment good first few rolls. With right starting rolls, it does not have to be P2W at all. Personally, I play the hell out of Puzzle and Dragons. You could ask your first question over at / rAndroidGaming in their weekly suggestions thread. You have to use in game currency to get most of better monsters, but they're pretty generous with it in game. The Power creep is ridiculous compared to what we had when the game first start, but almost all content can be beaten by F2P team / player. I'm fairly sure it was the first game of its kind on release, and everyone else just copied the matching mechanic. I don't play it as often as I did before, but I still log in almost every day to play a couple rounds. According to in-game records, I've been playing it for over 5 years.
