Unfortunately I have not played Mass Effect 1, but am immersed directly with the PS3 version of Mass Effect 2 in the ME-Universium. After playing through the third part, I must say a huge compliment but Bioware. I have spent countless hours all to discover, to learn everything and get everything. Especially the different characters I have grown really fond of. Without giving now content (spoiler), I wish to express a strong buy recommendation, because this game and this game series has a great story and an incredibly detailed and interesting game world. The missions are exciting, eventful and varied. For much criticized end I can only say one thing: I liked it very well. Thanks Bioware for this grandiose game.
