people wont care if they are nostalgic battles, they just want battles
i am not a fan of flippers but if you think about it its not too bad really, you do get a lot of variation, think of something like ripper, then look at iron awe, they are pretty different machines but still scusessful.
what we need its some more people to build the robochickens and robopigs, the robots that show off the more creative and fun side of things, sure they may be beaten by another serious but they look bloody good doing it.
and anyway, all it takes is a rx to fail or the link to come out or a wire to come out of place, could happen to any machine.
