An enhanced remake of 1987's Metroid for the Gameboy Advance. Visuals were upgraded to reflect Metroid Fusion, along with Samus' moves which now include hand-over-hand ledge crawling and sprinting. Players can also automatically save their progress to battery backup. There are also new cut-scenes, new boss characters, and new areas.
So, my rating's a 9 as I'm a big fan of the franchise, but it's undeniable as a remake it's ten times more fun than the first Metroid. I found the gameplay to be filled with cool tricky areas and features and sort of overall to be more adventurous than in other installments, although I played the emulated version and thus the experience and difficulty for me wasn't as hard as for some players. But overall I loved the atmosphere and the feel of it, the visuals, the creatures, the designs and areas, and you really can see the love they've poured in it. So I recommend it to each and every fan of the genre.
