What I love:
The interface and all of the systems, such as training, breeding and shopping.
Some games have a problem where you're very underlevelled and cannot pass a stage, but the Training system always allows you to catch up.
Breeding lets you get monsters in a way other than catching, which is very useful. Breeding also lets you up your monster's stats, making them a stronger monster in all.
Shopping is not too overpowered, so you cant just win the game by buying stuff, but the items in the shop always help out in tricky situations.
The graphics of the game are very cartoony and quirky, making the gameplay even more interesting.
And finally, the game itself!
What I don't love:
The fact that in PvP, you can play with people with much stronger monsters than you, or with much weaker monsters. This means that PvP is somewhat unfair, and winning is just based off of luck now, because you might be stronger than your opponent, or weaker. In 2v2, the same thing works for it too. You can get paired up with someone strong, sure, but maybe the enemy team is even stronger? I dont play PvP much because of this, and am discouraged to do so because of this fact.
Also, people always use monsters that are Rare, Epic, Legendary or anything near that, but Common and Uncommon monsters aren't used that much because most of them are not very useful. I myself use some Common monsters at times, but c'mon guys, Common and Uncommon monsters need some more lovin!
What I Would Like To See:
Ranks for PvP that people would be put into based on their Rating, so people can be put in a level where they have a 50/50 chance of winning or losing, and people would not have to be scared of the enemy having super overpowered monsters!
Trading! Perhaps you're in need of an item to evolve your monster (because of overpowered PvP enemies

) but you can't seem to get it. You have another ultra rare item that you dont need, but somebody else does, and that somebody else has the item you need. Why not trade for the item, and then everyone will be happy?
