I have to agree. Soul calibur has never had an endless stage, but look what we have now. And tekken has been doing that since tekken 3 i believe(correct me if i am wrong).Getting back to the enjoyable aspects of the previous games' engines and adding new mechanics previously seen elsewhere aren't mutually exclusive pursuits. If anything, multi-tiered stages are right in line with the ring out/wall pressure game (much moreso than an infinite stage)
