I was having a look at the Metacritic history for the Vita, and many of the launch and post-launch titles were actually really good. Now we seem to be in a slide of mediocre big-license releases.
One thing people seem to fear is that the Vita might end up being a hand-held console with ports of full console games, rather than having exclusive titles. The way things are going at the moment, as one person has already said on this forum I'm starting to wish they'd just start porting stuff, because the exclusive titles just are not cutting it right now.
