Huge fan of the series, played every game(Including Andromeda) multiple times, gone through many characters.
Legendary edition, while great by keeping most of the game original, has it's issues that the originals didn't.
1) Game lags on scenes. Words don't match up with mouths, kicks in a second after movement(or never, in some cases).
2) Heads up for those Solo Soldier types, big one for Arrival pack in ME2. When you're fighting the waves off at the Reaper device, one corner of the map is missing floor, and the game will treat is as a wall(died multiple times in the same spot until I looked down).
3) Lack of the multiplayer. One of my favorite things about this series was the multiplayer we got in ME3. The vanilla characters were good to start, but my fav pack i got was the N7 Earth DLC, which introduced revamped characters from N7. No PvP, all PvE, 4 man squads. If we got that, with some new maps, maybe some surprise characters(maaaaybe the kett?), would have sold me so hard on this re-release.
Overall, great playing, but because of the issues mentioned above, going to give 4 stars. By all means, anyone new or old to the ME universe, I would tell you to buy it, just know there's a few issues coming in to it.
Keelah Se'lai!
