Happy wars is actually a great game, it's enjoyable and funny + the multiplayer is top notch whenever it isn't lagging. Although I will emphasize on the fact that the game can sometimes be a pain with the "Pay to win". Players do spend money on buying little
packs to get better gear, but you don't need to. I had fun for the first few weeks on it without spending any cash and did quite well on it too. Can't lie though, gave into temptation and bought a few of those packs just to have some better looking gear. Try
it out if you haven't already though.
