It's hard to tell whether it is for licenses or whatnot since, if it was, they shouldn't have listed all of the games they do not have licenses for any longer (see how they listed a lot of sports licenses in that manner at the bottom of the list). On the other hand, I heard that they were trying to sell off any remaining licenses they may have but, honestly, I think most of those have already been taken back by most of the original companies.
And to be fair, Acclaim was fairly strong back in the NES and SNES days with some of their titles. Once the PS1/Saturn era hit, however, the majority of their non-sports output was primarily garbage, save for their initial involvement with SHMUP ports for the Saturn and their porting of various Bust a Move titles. Otherwise, their IPs and their non-sports licenses...oh lord, horrible.
They had a nice office in Glen Cove, if I recall, though. Beautiful building. They also seemed to be pretty big about inviting gamers in and testing their games for them, which was nice. On one hand it paid a decent amount or you got free food/chances to play some up-and-coming titles, but on the other hand it seemed that any suggestions made about bugs and errors found never got fixed.
