I started with a game similar to Super Metroid (I think it was called Mega Turrican) and with the real thing way back, but my first true exposure into Metroid scene was with GBA and Metroid Fusion which I loved. It was hard to beat.
Then came Metroid Prime, but I was not able to finish it on GameCube (I dit it on Metroid Prime Trilogy for Wii, where the wiimote seemed to be the one thing that I needed to really get my skills good enough to finally beat the evil Meta-Riddley). I really liked the first one in the trilogy but the other two are not far behind.
And I even like the last serious attempt at Metroid games, the Other M, which was a return to more 2D setting than the Metroid trilogy. I have gotten the other Metroid games from Nintendo eShop and played those too, but I am eagerly awaiting the next Metroid game. It seems that the makers of the trilogy (Retro Games) are doing something for Wii U, but nothing has been confirmed. I keep looking for new pieces of information from Nintendo Direct but nothing so far.
It seems that the storyline in Metroid is as difficult to piece together as it was with Zelda games. No official timeline has been established, so I was not bothered how Metroid trilogy was set in the general Metroid mythos. And maybe we have not seen the last of the Metroid Prime storyline yet.
