Campgrounds is a must-buy for me, one of the best TM games there is. That being said, Campgrounds IV was not as good as it's predecessor - but Campgrounds V is back on top. Great game. I'm up to about level 22, and this doesn't disappoint.
It takes between 10 and 18 seconds on my computer to load a level. That's not exactly a problem in my book. Great game, love the whole series, this is a nice addition.
I guess I'm in a minority here, but I really didn't care for this at all. There's no strategy required, just click the next available item on the path until you're done. If you don't make 3 stars, the answer is just to click FASTER. The characters are very cute, the story is very fun, but the game play is just.... boring.
