I am glad I started playing RPG games in 2009. Previously, I did not really understand the concept well, which caused a lot of frustration on my part. I remember buying Mass Effect 1 back in 2008, when the game was first released. I tried to play it like a FPS, and I desperately hated all the stuff outside the fights, i.e. walking from point A to B to talk to people and recruit them. I would skip all the dialogues, and did not wait to buy items or level up my companions. Result--premature death of the companions and my inability to progress much farther in the game. I think I stopped playing after I was sent to a distant planet where I was supposed to navigate the terrain using a rover. I didn't even know how to get my squad out of that car, and I got stuck in an area from where I could progress no more. Deeply pissed off, I uninstalled the game and didn't bother to replay it in about four years time.
So the Shepard in Mass Effect was actually me--I was taking all the decisions, and Shepard was just letting others know. I recruited all possible companions and waded through all the missions of the three games, trying not to skip many side missions. I did skip some of them in ME1 due to the tedious navigation system, but I didn't miss any in ME3 and only missed a few DLC missions involving a hovercraft like vehicle in ME2.
Apart from a few design choice flaws, the entire trilogy is an RPG gamer's dream come true, and if you have the remotest interest in planets ans space travelling, you will love to immerse yourself in Mass Effect's world.
The only grievance I have is about the ending. It couldn't have been worse. I won't give any spoilers here, but I surely hope they can fix the damage done with the epilogue video they are currently making.
