This game could be so great, if they had more constant updates. It's months in between content updates which sucks cause the combat is one of the best out there.

Not a lot of game play but has a short, sweet story.

It's a very grindy game, you will be doing daily quests for years and the more updates that come the more dailies there will be. However, there is a sense of progression in this game that is hard to find somewhere else and very well designed end game bosses with challenging and fun mechanics. At the same time has some of the worst upgrade systems in any game and its early game boss' mechanics are abysmal and make you want to quit. I do not recommend unless you enjoy very grindy games with a niche system of progression. The publishing company also does its very best to tarnish their reputation by introducing unnecessary nerfs, changes, and removals that negatively impact their users.
The game is also poorly optimized and prone to crashes, your tolerance may be different than mine, if you think you can deal with it go for it.

Edit (11.14.23): Reboot has now become Pay to Win with the introduction of the Sol Erda Booster/Cap. As a way to make us pay, they have capped our resource gain to a daily limit and have added an item to increase this cap. This is a ridiculous thing to add and has sapped away all excitement for the new content update. They have let go of Community Managers that have tried to speak up and have done nothing but provide a negative experience. Do not play, do not spend.
