METROID FUSION IS NOT AS GOOD AS YOU'VE HEARD!
The developers seem to have had only a passing familiarty with the metroid series(resulting in a few plot issues, and more importantly, at least one seemingly invincible bosses because it can't be hurt with missiles, which is the exact opposite of what one's instincts tell them).
And the game has some blatant flaws that get ignored all too often. Mainly in it's very heavy-handed method of ensuring you stay on the right path. The ship's computer locks doors on you. All the time. Anything not directly on the way to your objective is almost guaranteed inaccessable.
They took Metroid and ripped it's soul out.
Now then...
Circle of the Moon is great.
Aria of Sorrow less so. I found it boring, personally.
Lady Sia is a fun little platformer.
The retro-gaming compilations(Midway's Greatest Hits, Sega Arcade Gallery, Atari Anniversary, Konami Arcade Advanced) appeal to me. I like the old stuff. Your mileage may vary, but given your admittedly short attention span, they seem right up your alley.
