| Prime 1 and 2 were released for the GCN, meaning they are incompatible with the very-competent Wii editions' controls, unless purchased in the Trilogy. Additionally, there are more extras included a small printed art-booklet, some minor textures have been improved in the earlier games, and MP1 includes the voice acting that only the PAL versions received. The enemy count has also been increased in certain instances, to accommodate the much more responsive controls. Similarly, Metroid Prime 2 received significant extra tweaking to make it more playable, because of certain unintended difficulty spikes that plagued the original GCN version.
Notably, in Prime 1 (and presumably 2) some lens-effects have been removed from the charged up beam-cannon in favor of a free-moving cannon that follows your aim. Strangely, the water ripple effect has also been removed from Prime 1, although no explanation was issued for that effect removal, to my knowledge. |
