To be honest, based on that comment I cannot think you have played the series much. It has a loads of depth and variety of moves throws combos, juggles etc, and this is just talking about the previous gen incarnations (Tekken 1 - 5).
Have you ever played the Tekken games competitively or with a proper arcade stick by any chance. At the Arcades it is the best 3d fighter I have played.
I guess its down to personal choice, but not a basic game by any means.

Edit: In hindsight I may be biased having played all the games in the arcades, on all the playstation ports, and having arcade stick and having played in tournaments
