i really enjoy the first game a little more. i think the overall flow and pacing of the first one was more pleasing. i didn't like the beam weapons in echoes as much (especially hated the ammo system). i didn't care for the lessened focus on franchise staples. i thought the boss fights in echoes where harder but i thought the bosses in the first game where more fun. one boss fight in echoes was particularly boring during the first stage and it took forever to get to the fun part. i didn't like the order of the upgrade path as much in this game either. in just about every way, except for graphics, I think the first game was better. this game is still an extremly high quality title and easily the best cube game i have played this year.... probably one of the top 4 or 5 games i have played this whole generation actually. but i felt prime 1 was in that extreme upper tier of all-time games and thats hard to pull off twice in a row.
