Post-Review Technical Questions and Answers: This section is meant for those that have already played the GameCube versions of Prime 1 and 2, and may wonder about the Wii ports. Those not familiar with the original releases may not gain much from this section, however.
Are the graphics improved?: Yes and no. Yes, in that Prime 1 and 2 now support widescreen display. No, in that some graphical changes appear to be intentional adjustments rather than straight upgrades. I admit I did not get to spend much time with the GameCube versions however and cannot answer this in exhausting detail. Regardless, the games all look fine on the Wii.
Is Metroid Prime 2’s multiplayer included?: Yes. It seems to be very similar to the original version. Note that online play isn’t provided, making this a local-only activity.
Are my save files from the original games compatible with Metroid Prime Trilogy’s versions?: No. This includes Prime 3; the original release cannot interact with the Trilogy version, both in terms of save files and unlockables (plus assisting friends with them).
Can I use GameCube controls with Trilogy?: No. You can only use the Wii Remote plus Nunchuk.
Is the original NES Metroid unlockable in Prime 1 on this Trilogy disc?: No. The only way you’re going to ’unlock’ it in this case is to either have the the original GameCube version of Prime 1 and unlock it there, or buying it from the Wii Shop Channel.
Any other noteworthy differences?: Yes, two in particular. First, the unlocking system used in Prime 3 also applies to Prime 1 and 2 in this release. Also, some adjustments have been made to the games to correct glitches and tweak other parts of the experience. An exhaustive list of changes is beyond the scope of this article.
