considering getting a 360...

I have a ps3, a wii and a decent pc, but right now i've been on a crazy rpg kick and i've been a little upset that i couldn't get my hands on tales or so4. On the other hand, Given how cryptic the developers have been about if these titles will be released for ps3, I would say both have a good chance of crossing platforms. The arcade is only 200$...and there are still a few exclusives that interest me.

So my question is this: if i don't plan on playing online w/ the 360 (i'm not paying a subscription fee) how much does not having an HD affect the games? Are some of the downloadable arcade games really worth getting a 20gb?

so besides tales, the exclusives i've been eyeing are LO, GeoW, fable 2, maybe infinite undiscovery and NG. I'll probably play halo if i end up getting a 360, but I'm not a big fan. Are there any other titles that are exclusive (real exclusive...not console exclusive) that are worth looking at?

i've played mgs4, and i'm not super into console shooters. I'll probably play resistance 2 one day...but i'll never buy that. That's like 12 hrs of gameplay with no real MP draw considering how spoiled i've been with pc shooters. Much better latency and never a lack of servers to play in...so yeah.

Anyway, thanks for the tip about the 20gb, i think i'll go w/ that if i can find it pretty cheap. i'm scared of refurbished 360's though for obvious reasons. My biggest concern is if the lack of an hd will drastically affect loading times.

And are there any other worthwhile exclusives?
