Look at those games you listed, those aren't popular by any means.
Twisted Metal - Reboot. It actually sold pretty well considering its a pretty niche genre.
Starhawk - New IP. and its a shooter. Had no chance. Hell even Killzone series which is extremely high quality has trouble selling against the Call of Duties.
PSABR - It's a 2D side-scroller fighting game. Were you expecting 1 million FW or what? For comparison, Street Fighter x Tekken did 119k FW. So I'd say PSABR is off to a good start.
LBPkarting - Another "core" Sony game being spun off to sell to little families. There isn't a big market for family games on PS3 especially not for new IPs.
