I had a similar experience with Alice: Madness Returns. I was ready to try an "unofficial patch" to remove the activation/copy protection when it finally started working correctly.
Yeah, I found the recipe to make "MASS EFFECT" to start, but I have to do every time the ONLINE launch + OFFLINE launch to actually play it...
Luckily, at least, the game seems pretty stable once I start to play.
I suppose to be at 1/3 of the game, and I'm a little disappointed, considering all the good reviews I have read in the years.
It has some good cinematic moments, but it is very repetitive... also, you "have" commands to control your squad members, like "move there", "stay in position", etc... but in the end those are working 30% of the time... at least the squad members are somehow autonomous, they keep cover and use their skills in somehow the right way.
The Planets exploration part could have been a cool thing, but in the end is just boring, and consists of:
1) click on a galaxy
2) click on a solar system and goto 3), if it was the last system goto 1)
3) click on a planet and goto 4), if it was the last planet goto 2)
4) if you can land to the planet goto 5) else goto 3)
5) you got the same landing cinematic for every planet, only the background changes, all planets are empty and lifeless, excepts for some rare gigantic worms
6) use your ATV to reach one of the points of interests on the map, then goto 7) or if points of interests are finished goto 3)
7) - if there's a base enter and kill everything (the bases are all copy/pasted in the entire universe)
- if it's something else (a mineral, a relique, some scraps) just do the usual "hacking minigame" to get the content.
then goto 6)
"MASS EFFECT" seems really really similar to "STAR WARS: Knights of the old Republic" under almost every aspect, but I found the latter more entertaining and less repetitive.
I hope that in the next two games it will become better.
