Arknights 12+

Wayyyy more fun and enjoyable than you could expect! I wasn’t expecting much at first glance but there really is so much depth and care taken in the making of this game and its one of the most beginner friendly, F2P friendly gacha ever. They are extremely generous with rewards and very balanced, all units are useful and there isn’t one particular unit you MUST have.
Gameplay is extremely satisfying, not tedious, and the WORLDBUILDING IS TOP NOTCH. If you’re a story enthusiast, there is so much lore and it is obvious much care was taken even in the little details to build their world and characters. All the characters have unique personalities, they are written well and despite appearances none of them are shallow. The art direction is distinctive and well done. Gameplay wise, you’re not forced to attempt everything and can play casually at your own pace without fear of missing anything, which is rare for gacha games and extremely refreshing.
But most importantly, THE MUSIC BANGS!!!
Everything they do just shows how much they love their players. They always frequently give back to the community and treat players well. The fanbase is also great. Really underrated game.

⭕️No PVP so F2P and P2P friendly, advance at your own pace
❗️Originum becomes scarce later so save it if you want to use it on refreshing energy or buying skins (15~18 originum)
⭕️Great animation and character design
⭕️Floors are challenging but possible with lower star characters as long as planned well
⭕️Upgrading units are not RNG based
⭕️Cute Skins

Sad to see people complaining about gacha rates; you can pass every floor currently released with no more than 3/4/5 stars as long as they’re built correctly and timed correctly (not sure after the update though).

The 2% pull rate increases over time and a free system called recruit allows (a very low) possibility of pulling 6 stars and many 4/5 stars which provides decent progress. If you want a certain unit, to some degree you can see what comes next when online since global is still catching up to China server. So save up your large amount of red crystals you get weekly until your wanted unit comes back around.

The game has great art, amazing skins, great dorm designs, is easy to understand but challenging to pass at times (which makes it very addictive) The game can be played from start to finish F2P, but spending definitely seems worth with the amount of effort put into the game.

I can't believe I have not played this before... it's got ACTUAL strategy (not just dumping the best characters into random positions) and even the story is good. Battle is surprisingly fun. Rewards are pretty balanced. I don't get what everyone means with 'bad gacha rates'. The rates are literally the same as every rpg game ever.

Another great thing: You don't actually need the most op characters to win all the rewards or anything. You can have the worst characters in the game and, if you deploy your tactics well, you can still win. If that's not f2p friendly idk what is.
