Yeah, you could get a lot of kicks by zipping through the levels and hitting all the tags as fast as you can, but there's no sense of urgency because you're never being pursued while you're doing this, nor is there a time limit. I like that Smilebit added huge graffiti that required several sprays to create (this is cooler than the single-spray images you can tag while grinding in the original), but the game might as well be in god mode while you look for tags because there's no resistance and health cans continuously regenerate — and with no time limit, it's basically impossible to die when in this mode.
I wish they had kept the tagging minigame mechanic coupled with the time limit and increasing resistance but with bigger areas, bigger and more interesting graffiti, and more ways to interact with the resistance when the heat turns on. Having two inferior modes — one where you spray tags with infinite health and no enemies and another where you're put into a tiny arena and skate in circles repeatedly to defeat your enemies — wasn't what I was expecting from the sequel. And don't forget about the horrendous padding that happens later in the game, like being asked to revisit old levels to bash into stationary enemies that don't put up a fight and...that death ball race bullshit.
