Bumping this thread because there's a free demo going on right now for this game and I finally checked it out. I honestly only had minimal interest in this game. I hate to say it, but it seemed very "For kids only!" Plus, there's plenty of other games I want for the system that I haven't gotten around to picking up yet.
I played last night for about two hours, and surprisingly had a blast! I'm honestly considering picking this up for some casual online play. The paint mechanic is fairly unique, and I like how the short matches encourage you to play just one more round. I'm even pleasantly surprised by the gyro aiming. After a while, it started to feel fairly natural. Even as someone older than the target demographic, I kinda dig the art style - sure, it's very Nickelodeon-esque, but the bright colors are definitely a breath of fresh air.
It's not perfect. Part of my hesitation with picking it up is the longevity question. Will this continue to be fun in the long run? It definitely has it's hardcore fans that have hundreds of hours logged into the game, so I'd say it probably depends on the person. Right now, servers are plenty active, though this could be because of the free demo. Finally, who's idea was it to have only two maps available at a time? Is it that hard to just rotate through all the maps? I really don't understand the logic behind that.
Overall, I'm having a fun time. Not sure if I want to drop $40 on this (let alone the $60 that it normally is!), but I'll keep playing for the next week while the demo is still active and reassess after playing a few more hours to see if it has any staying power for me.
