WHOA, YAHTZEE! SPOILERS!! I did not know that Splatoon had that many maps going on right now... Glob! Way to ruin the surprise...
OT: Well, given how Splatton does their map-matching as well as the one time I got a chance to play it (and became part of the winning team as a result), I find it to better than how it is in MW2 and MW3... Seriously, both those games have over 10 maps and, yet, my and my friends always choose the Terminal... If those games did what Splatoon was doing, we would, at least, be trying out the other maps in the process...
Other than that, in general, as long as it doesn't impede the game's "story", I can't personally complain about it because I just wait until the GOTY/Definitive editions to come out, anyway...
