If you like to game a lot you should probably go to Crown. But put schooling as your priority, one of my hall-mates withdrew from all his classes this quarter because he was failing all of them. All he did was play video games all-night. He would play till 4AM. He even missed a midterm due to paying video games. He's coming back next quarter but he wasted a lot of money for no reason and is behind a quarter now.
Another thing, there's not much partying in UCSC. And the few parties that there are, you have to have connections to get in them or actually join the frat throwing the party. During welcome week, I went to a few frat parties and they were lame. College parties are definitely not like how they are envisioned in the movies and TV.
