Here is a glimpse of how 33,000 tracked players approached Super Street Fighter 4. And I'm sure its similar across each platform and each version of SF4.

Only 60% of all players even completed Arcade mode on a medium or higher difficulty.
61% of all players completed 10 trials.
16% of all players fully completed at least one character's trials.
38% of all players have managed a 3 win streak in Ranked.
28% of all players have reached Rank C with at least one character in Ranked.
44% of all players have managed to win at least 10 ranked matches.
40% of all players have played 50 matches online.
55% of all players have played in Endless Mode.
Okay so SFV has no trials out cinematic story out f the gate. No 8 player lobbies. Look at those stats. They don't care.
You can't save every casual. Some of them don't wanna be saved! I'm sure everybody here has played a game in their life casually and never wanted to do anything more than that with that particular game.
