Phantasy Star Online NEEDS to be on XBLA. A few things would need to be cut in order to make it cost effective, namely, no dedicated servers. Still, a modified version of the splitscreen would suffice, allowing players to act as their own server instead of relying on an outside source.. PSO to me is the perfect modern day reinvention of games like Gauntlet. A 4 player extravaganza where you kill tons of monsters and level up. Obviously it's a bit more RPG than Gauntlet, what with all the collecting rare loot, different weapons, etc. but it still fits the basic Gauntlet formula pretty closely...it certainly plays more like Gauntlet than it does the original Phantasy Star or modern MMO.
I'd expect all the content from Episode 2 and Blue Burst/Episode 4 to be available, either initially or as DLC, whatever. Maybe even Episode 3...but that's really so altogether different it would be better as a separate release altogether...altogether.
PSO is one of my personal favorite Dreamcast games, and I think everyone should experience its greatness. PSU just doesn't live up to PSO (even though it isn't terrible by any stretch of the imagination).

On a game like PSO, you're either limited by incredibly time consuming/hard achievements, or nothing but run of the mill progression achievements. To compensate, I figured going 50/50 with easy achievements and hard achievements would be a big intensive to most people.
I like playing a HUcast, Red and White like a Dreamcast.
