As Mero said, and even if it were, there are people, myself included, who enjoy using Red Power's power system. IMO, it requires a fair bit more forethought than IC2 or BC/TE power, since it works more like real-world electricity than either of the others do.there will be footballs with lasers, a catalyst laser, and more laser stuff.
MJ and EU is enough, I don't even know why do we even have bluetricity or why to do a new form of energy.
Hell, I enjoy Xycraft now, just for the aesthetic appeal alone. Being able to turn anything harder than wood into a gigantic tank? Hell yeah! Yeah, RailCraft tanks can store more in less space, but they require more in terms of both resources and infrastructure. You can also blend the Xycraft tanks into your base, should you want to, going by what I've seen in Direwolf's videos. On single player, aesthetics may not be too important, but I can see it being a selling point in SMP. One-upping one another is a grand human past time, after all.
