The external drives are just going to be trouble and expense.
As to DATED INFO, nothing has changed. For example Spy Vs. Spy didn't play years ago and still does not. You have to research each title to find out which does or does not play. The arcade version makes the compatibility worse since any download is not possible for xbox live to make the old game work.
My vote? No arcade version.
I am about 3 years behind the rest of the world (smile) and am finally at the point where I may be purchasing an XBox 360 for Christmas for me and the family.
I have the original X Box with of course a box full of games.
Here are my questions:
1) I know I can play some (maybe most) of my old games on the new xbox 360. But is there one place I can find a list of what games I can play and which ones are not backwards compatible?
2) I am most likely buying the xbox 360 arcade version. Is this an issue? I THINK I read that this model does not have the hard drive, and thus I would need an external one to handle playing the old games. reason I am going arcade version is I have found a killer bundle deal with that and guitar hero band kit which is ultimately what is causing me to perhaps pull the trigger on getting a 360
3) Anything else I am missing?
I tried web searches for all this info, but as you can imagine most of the info I found was OLD from when the xbox 360 first came out. It does not address the 360 arcade
