That's a great number to have, and roughly twice as much as me. It's all relative though, so it all depends on what else you ahev and colelct for. If these were your only consoles and the only ones you buy for, then those numbers are justified and relative, whereas someone like myself spreads my buying across many more consoles, and therefore can't allocate as much cash towards collecting for the current-gen.
However, if indeed you do collect for many other consoles too, then that's excellent going! At the moment though, i'm more interested in chasing older games I missed last generation and waiting for games from this generation to drop in price, with many games I do have being LE's and CE's which I had to buy on release day as they would be harder to source at a later date. DS games are relatively cheap, hence why I have more than any other, and PSP games are picked up here and there for peanuts whenever I can be bothered to scour eBay for bargains
As a general rule though, I mainly stick to the main franchises, so many of the other games I have from this generation form part of a sub-collection, such as Resident Evil, Pokemon, Metroid, Final Fantasy etc...
