No.
I don't think there is enough games that would warrant your purchase (Either today currently or into the future). I don't want to generalize the 360 as a shooter box, but let's face it. The most popular games on the system, the most active online portions for games, etc is primarily shooter-centric.
I just don't see many games that are worth your time, money, effort. People are suggesting games like Halo Wars, Banjo Kazooie, etc..... While these aren't 'bad' games I certainly wouldn't quantify any of them as games worth buying a 360 for. Many of the XBLA games are usually available on PC as well and a good portion of the non-shooter quality 360 games are Multi-Platform. Wasting money on a console for minor variances in Multi-platform titles is also equally foolish, IMO.
I honestly believe a Wii would provide you a more diverse, varied experience more compatible with your tastes and what you're looking for. Save your money and gobble up all the great PS3 exclusives releasing this year, and make a decision by the end of the year (After price-cuts and E3).
