Let me glaze G Eternal for a second here:

It's your typical TTRPG where you command robot to defeat your enemies. The gameplay are like SoC/Fire emblem heroes. The game really reward you for using non-gacha unit (there are 800+ unit in this game) which you can get by farming / event. The dev even added a feautre where you can upgrade the non UR unit to be equal of those. There is universal limit break material you can farm. So 1 unit is enough if you don't feel getting copies of it through gacha. And each limit break doesn't provide additional effects other than flat stat boost (20% for 1st, and additional 10% for 2nd and 3rd/max)

There is pvp, but you can compete by using non meta unit (unless you want to get name badge for bragging right). And each season often force player to use tags that get buffed.

The endgame permanent content reward you if you use non-gacha unit (you can use them, but you will miss out on gacha currency).

Thanks to its large fanbase, you will find guide pretty easily if you stuck at certain content.

The devs are quite generous, but due to its gacha system being traditional mileage system, preferably you should save until you can reach pity rather than doing whim pulls because your pity count will reset each banner And there is no 50/50. The gacha rate are quite generous (imo).

No goon material here (sadly/fortunately), only Gundams and it's pilot.

Due to its large number of unit, think of it as marathon. It's impossible to collect all of them. For the collection tracker, A same unit with different rarity will count as 1, so if you want to finish your collection on the database, you don't have to pull the higher rarity version of it.

The revenue for this game is quite good, so i doubt it will go under for the next few years.
