When Puzzle Bobble was all the rage, it would have been great to see an official version and I'm sure the Amiga was more than capable of running it.
I also can't find official verison of things like PacMan, Space Invaders etc. There are clones but thery all have slight variations or enhancments.
It would also be nice to see re-works of some of the arcade conversions which WERE released but were poorly converted like Turbo Outrun.
Some more of the original Command and Conquer titles would be welcome too.
