Mass Effect is an awesome game, but lets face it the plot was horribly riddled with problems from game 1. 1.(most obvious) Why didn't Saren just activate the Citadel Mass Relay while he was still trusted. Why openly betray anyone or invade with the Geth when the Reapers could just be summoned from the get go? 2. The conduit. What was the point of it? If you remember, the Normandy is grounded at the citadel and Sherperd has to escape to pursue Saren on Ilos. All that ends up happening is you arrive on Ilos only to be told the same thing about the reapers from a Prothean VI that you have heard already and then transport yourself back to the Citadel. If all the conduit does is transport you back to the Citadel why even bother spending the entire game searching for it? If this was Sarens plan all along, or worse yet Sovereigns plan, it can be safe to say that the "reapers" have either become really arrogant, really dumb, or else the Protheans and all other civilizations before them were even dumber. 3. When Sovereign attacks the citadel it easily bypasses the defenses and alliance ships and gets in the station. If it was that easy to surprise everybody why not just do that in the first place with Saren on board and get him to activate the Citadel Mass relay that way. Sovereign literally just smashes into other ships to get to the Citadel because it is so huge. It would take no time at all and there would be no reason to involve the Geth or search for the Conduit. 4. The reapers themselves don't make much sense. I guess they are supposed to be mysterious and alien but the whole argument against advanced Organics building Synthetics that is put forward in later games just does hold up. The concept of the Reapers is fantastic, but they really should have put more thought into their motivations and their true nature.

Sure Mass Effect games are awesome, but as far as plot is concerned they don't hold a candle to games Knights OF the Old Republic (also Bioware) which to this day is one of the best Sci-Fantasy stories of any role playing game. Even Halo has less plot issues then Mass Effect.
