While I don't own either game, get Kirby
.
From what I saw of it online, the game looks like a wonderful sequel to Returns to Dreamland (more copy-abilities to use, the "super" ability being far more interesting this time out, the game is one of the few 3DS games that make great use of the 3D, and the game does get some challenge to it too). If you enjoyed any of the traditional 2D Kirby games, then get Triple Deluxe, you will really enjoy it
.
With Watch Dogs....I don't know if this is a fair assumption (as I don't own it), but it just looks like another run-of-the-mill open world game
. Bland visuals, the 'hacking' really doesn't look like it does much (outside of making thing's easier for you....looks like you can get money quick from hacking people's bank accounts), the gun-play isn't anything special and Aden looks like a really bland character as well
. If you are interested in it....just watch some gameplay of it or rent it from Red Box (I saw the PS3 version their as a rental option; one day (which costs 2 bucks) should be enough to see if you like it or not) to get a better impression of it :l.
