Promethean has its intimidation factor almost maxed out, with its unnaturally tight looking ship gaps, extremely simple-to-process gameplay. It's also themed around hell which helps a bit, although the slight creativity in portraying its theme matters much more.

As for the negatives: its greatest strengths are also its greatest weaknesses. It's not that interesting to look at after the first time you watch it. It's not like Promethean uses an interesting gimmick, either. It's just straightfly. All this combined balances this out to become a fairly average level for me
