Can't beat free
A lot of the games that are shown off this week are going to cost cold, hard cash. Sony wants to alleviate the stress on your wallet (probably). As part of its press conference today, it showed off a montage of free-to-play titles that are coming to PS Vita.
One of the standout titles was Fat Princess, which looks to be some sort of match-three puzzle game. However, there were a handful more, all available to anyone that owns a Vita. We should find out a lot more about these in the very near future, but we already know exactly what it'll cost us.
