I didn't play yet, planning today, but heard there can be long delays to join. I guess it's an Alpha so to be expected.
I finally played some over the weekend. It was fun, but the games didn't last long and the only way I see them lasting much longer is if the monster keeps running from you trying to "evolve" and grow. Then it might get boring as there is little to do except chase the monster.
I think it needs more sub missions and things to fight/do besides chase the 1 monster.
There are some YouTube videos of it with people that really seem to know the game and it looks a lot more fun. They know how to unlock the skills and build up and all that.
It's only a limited alpha test so I am expecting a lot more when the beta hits.
