A dream is gone!
Main quest and side missions are fun, even if you are overwhelmed by dozens of enemies, lacking sometimes the indications about what to do next. I like the lore behind them, but I disliked the necessity of multi player to enhance your war readiness since i like to keep my single player experience separated.
Upgrading armors it`s not an option, leaving you with sets or parts who make the life of soldier or vanguard easier, while sentinels, my choice, will end up with Collector Armor. Mods for weapon are nice, but limited in options for assault rifles, for example, while shotguns or sniper rifles get more interesting upgrades and Spectre gear.
I`m not going to criticize the way defensive and offensive biotic or tech power got nerfed because biotic combos are powerful enough to carry you through the end of a normal play and overload will chain stun almost everybody. There are no OP classes anymore and team members will get some type of shield like fortification or defense matrix, compensating the way tech armor got from "kaboom" to "meh".
The ending is not in tune with the rest of the game. After 150+ hours invested in three games, making my own decisions and hoping, at least, to die by my choices, I got a strange final. It's not possible to be on top of the Reapers in the single player. The result is synthesis, since I was even with Reapers forces. I don't know if the devs had to face budget cuts and skip the effort necessary to put together all possible endings or we'll get, I hope, future DLC as part of a marketing campaign, opinion supported by Indoctrination Theory adepts over the net. ME 3 IS the best game in this trilogy and I'm proud to know Commander John Shepherd.
