This game can be really fun but every game had its pros and cons
Pros:
Its pretty fun to collect the monster and have allies
Lots of bosses
Rewards for every event even when you are last
You can level more
Than 300 time
Got many qeust
Cons:
You have energy to use and if depleted you must wait and can do nothing.
Higher levels or beter players have always beter units and ranking in events
When you just started you will be attackt by higher or better players.
It can be laggy if you doesn't have good connections.
Doesn't have bosses only for beginners or just started players
When you combine monster it can be really expensive
Must have connections to internet
But overall its à good game to play. 3/5* - 4/5*
