Based on the ending of Mass Effect 2, does anyone else think Mass Effect 3 will most likely be similar to Dragon Age Origins in the sense that it will be about securing military aid from numerous factions to confront the ultimate threat?
Based on what we've seen so far the reapers are a threat to everything that breathes and even some who don't, so the parallel with the darkspawn/archdemon is evident.
As for the people we need to get involved with the war, we have the Systems Alliance (Citadel council and the Alliance, may still need persuasion about the reaper threat), Cerberus (more or less ready, may be affected by whether or not you handed over the Collector station at the end of ME2), Terminus Systems factions (possibly united under Aria? Mercenary groups?) the Krogan unified under Wrex (if you/Ashley didn't put a bullet in him), the Quarian flotilla (Tali's sidequest and the choices you can make there strongly hints at this), the non-heretical Geth (Legion plotline, related to the Quarian stuff obviously, could be a one or the other situation, or both if you are persuasive) and we have the Rachni and well as the remaining non-council races on the Citadel.
Can't wait...
