this set is hands down amazing. that is the best word i can use to describe this game, amazing. getting 3 full games for the price of one isn't good enough for metroid, oh no, they redid the controll schemes for prime 1 and 2 so beautifully that they play exactly like prime 3. a hardcore metroid fan like myself can surely tell you that this game is worth buying even if you already own prime 1 and 2. i was never able to defeat the final boss in prime 1 sadly because i couldnt aim at it. simple as that. and now that i rented this trilogy with intent to buy, i was able to breeze through prime 1 2 and 3 on the veteran difficulty setting. the revamped controls in prime 1 and 2 really make this worth buying even if you already own the gamecube versions like i do, i was lucky enough to have waited on buying prime 3 and then i heard that this set was coming out so i bought it and very glad i did.
Each one of these games are very lengthy, especially if you take your time to get 100% completion. the stories are presented in a neat way if you enjoy scanning each room you come across, (which also makes it easier to solve puzzles) scannable objects will reveal partial bits of information concerning the history of different species and planets backstories.
I didn't get a chance to play the first two titles on the gamecube, and i was very impressed with the control scheme. it felt very natural after a small learning curve, far better FPS controls then some other shooters.
The momentum of gameplay and story progression are very fluid for the first two-thirds of the games. after that it slows down to an almost boring pace while players are forced to do extensive backtracking to collect items required to move on.
other than that, it felt very much like what one would expect from a metroid title and more. I'm very much looking forward to the next game in the series.
