I'm not really considering it for RUb, as I'm trying to slowly extricate myself from the SH3 modding business and finishing tying up all RUb's loose ends, so I'm trying to avoid getting involved too deeply in major mod additions unless they really scream "RUb REALLY NEEDS ME!!!"
I'm more interested in it because it's kind of the 'new player on the block', and clearly people enjoy it. The name made me curious as well, but it made me suspect it of arcade tendencies.
