It would seem that _Raging Blast_ was ultimately Spike and BANDAI's best effort at making a Tenkaichi game, and afterwards everything just became stale for them. _RB2_ was like an expansion (much like Dimps' _XV_ and _XV2_ more like XV 1.5) and _UT_/_UB_.. Well, pretend that never happened (except for the awesome graphics and anime cutscenes). _Raging Blast_ on its rear covers even mentioned "Next Level Tenkaichi" so they really were aiming to make RB as "Tenkaichi 4", just without calling it "Tenkaichi 4".
