nope sorry. bit insulting to suggest that solo hasn't played the game when he obviously has.
this is what solos complaint is.
in me1, the side quests were quite in-depth and had alot of variety. some of them built upon others but generally the majority of them had a plot to them. tackling Cerberus, the a.i, the guy on life support, and so on. they managed to roll exploration, combat and plot into one nice package. sure, there was gameplay and repetition issues, but the main idea behind them was correct.
in me2, you search a planet, find a beacon, and you go down and kill some stuff for about 10 minutes and leave. its streamlined, gives you no plot or motivation, its boring, doesn't extend the universe and it lacks the exploration and freedom that me1 had.
edit: putting aside that you compared a main mission with a side quest.
