The best RPG I've played - a masterpiece plain and simple
Gameplay - Improved over ME1 & ME2. Nice selection of weapons and a wide variety of mods available for all the weapons. I imported my character from ME2 which worked out for me as most of my squad survived the suicide mission at the end of ME2. That allowed me to rekindle friendships from before. I choose Infiltrator this time around over soldier, and I was pleased. You can be a sniper killing machine if you want. I highly recommend all the side missions. Some have excellent battles and the others are improved as the constant scanning of planets for resources is vastly improved. Besides, doing all the side missions builds up your war assets needed for the final Reaper showdown. I went heavy Paragon and enjoyed the experience. Note: you must select renegade at the end. A little shorter than ME1 & ME2. I got 32 hrs in doing all side missions compared to 38 for both ME! & ME2. Time varies depending on whether you go casual or max difficulty. Excellent boss fights, some are really tough.
Sound - music and sound effects were spot on. A little War of Worlds, Star Wars, and good music mixed to heighten the game play experience.
Controls - Straight forward, much like ME1& ME2. No problems playing from PC with keyboard and mouse. Camera angle is just right through out. I also like the "v" key to show you where you need to go.
Replayability - With the option to play as a biotic, engineer, soldier, and others along with Paragon and Renegade options, the entire series is a must replay starting from ME1 all the way through.
Graphics - Eye candy through out. Colorful scenes, excellent graphics, lip syncing was great, cut scenes are a joy to watch.
Bioware & EA did a nice job. I now have to check out their Dragon Age series since this was so good.
