So today I got near the end of Mass Effect 3 and was wondering why my readiness rating was stuck at 50% all the time. The readiness rating modifies your effective military strength in the final battle. I got around 6300 units with a pretty decent ME1&ME2 savefile and due the readiness rating of 50% only 3150 of those will be used for the final battle. 5000-6000 units are needed for a "good" ending. So how do you increase this rating? By playing multiplayer and that's what it is all about. Pirates won't be able to play online at all or at least have to buy the online pass and people who bought it used also have to buy the online pass. And on xbox 360 you also have to get Gold. I read with a 100% perfect ME1/ME2/ME3 savefile you can get to a strength of 10000 which so far only seems possible on a PC by editing the savefile directly. So I'm wondering will future games do the same, require that you play multiplayer to get the best ending or worse even prevent you from advancing?
