Yeah, it did have a decent showing...but there still just isn't enough to draw me in.
Castlevania is the one game I REALLY want, but if I DO purchase a DS, I'd probably also enjoy Mario, Sonic Rush, Phoenix Wright, Nanostray, Lost in Blue, and Kirby. That's 7 titles total right there and I'm sure more will show up down the road.
PSP really did disappoint me, though. I love the machine, but the E3 lineup should have been much stronger. Out of the E3 list, I'm interested in Burnout Legends, GTA, Infected, Coded Arms, MediEvil, GG Judgement, Daxter, Acid 2, Virtua Tennis, Ys VI, Lemmings, Pursuit Force, Crisis Core (not that anything was shown), Death Jr., Sonic, PoPoLoCrois (MAYBE...)and a couple others. I guess that's a pretty decent list, but I think my disappointment stems from the lack of new announcements. I was expecting most of those prior to E3. Then again, outside of Mario for DS, there was nothing new that I want on DS either.
I think that's where most of my disappointment comes from. There was very little introduced and I really didn't need anymore info on those other games.
On a side note, the two systems had an equal number of games at the show. According to GameSpot, they both had roughly 70 games present (with PSP taking the lead by 2 titles).
PS2 is pretty loaded, though. GC is basically dead to me (only one game left) and XBOX is almost there as well (which makes sense, considering the 360 launch). Not much on the PC side either...
