I have spent 130+ hours and I did not see pass the time. Being able to import their character from one episode to another, and that the choices (shares / romances etc ..) that we have made are kept in episodes further reinforces the immersive side.
ME1 accuses a little his age for textures but it's still okay: and then we made the atmosphere so it goes (very) well. Note that the fans have released an HD texture pack that improves some aspects
ME2 is for me the most successful component with good game balance / atmosphere / active / exploration; The also can boost textures thanks to fans packs.
ME3 against abandoned by the side a bit too exploration and has many video clips. It's good for the story, at least for the gameplay. But we are so taken by the story it out. The weird thing though, is that the multiplayer multipart you pretty much have to do to increase the level of preparedness of the armed ... es of the solo part (which affects the end) !
Regarding installation:
1) download the latest program on the Origin site, and do not use one that came with the DVD. Even if it is updated, this is not the latest therefore risk bugs.
2) I had the problem on installing ME2 with errors in reading. I got out a copy with another DVD player all DVD to the HDD, and launching the install to HDD part of
3) launching facilities in time quadministrateur
4) ME3, the installer patch as on the other aspects, but it also lowers the Extended Cut DLC containing the "new purpose". I saw the bloody controversy on the old purposes. Personally, I found the end chosen quite consistent: the DLC should help
In short I have only one desire: it is again!
