9. Virtua Fighter 2 - Sega Mega Drive
Sticking with fighters for a minute, this entry is an example of a port which completely missed the point of its parent title.
When Virtua Fighter hit arcades in 1993, it was hailed as a huge step forward for a genre which had hitherto been the realm of 2D fighters like the aforementioned Street Fighter series, Mortal Kombat, and Killer Instinct.
Boasting fully 3D, motion captured characters, 3D arenas, and introducing "Ring-Outs" as an alternative to "Knock Outs", Virtua Fighter set new standards in the one-on-one fighting genre.
Home console versions soon followed, with strong showings on the Sega Saturn and Dreamcast, and later on everything from the Nintendo GameCube to the Xbox 360.
There was also, however, a Sega Mega Drive version.
Given the dated, 16-Bit technology ("Blast Processing" notwithstanding), Virtua Fighter was just too much for this ageing system to handle.
Gone were the smooth, 3D characters and stages, gone was the dynamic movement on multiple axis, in favour of a more generic 2D, Street Fighter-esque game.
Had it not borne the Virtua Fighter name, the title may have been considered a competent if not stellar 2D fighter, but as a port of the fully fledged Virtua Fighter parent title, it is truly terrible.
