06 is a fundamentally broken game. The design is offensive, its technical issues are rampant.
It is objectively worse than Colors simply by the fact that Colors is a complete, actually-competent title.
There are actual gameplay elements missing from 06 that were skipped due to the rush to stores. The game was barely (if at all) playtested. The game was so embarrassing to the franchise that they retconned the entire events of its abortion of a story in the ending sequences. In addition, SEGA ordered that copies of the game be removed from the store so that no other unfortunate soul would have to endure its incompetence.
Either you are trolling, or you have no concept of what video game design means, as well as the inability to spot an unfinished product from another.
You may not like Colors, you may not like its story, gameplay, sound, design, WHATEVER. But to say that 06 provides a better experience than Colors is nothing short of incomprehensible.
Fuck, there, I said it.
