Things you wish would've happened in the trilogy

I disagree, once I've released Stellar and Spectre mods for ME3, my aim is to look at how to add npc's to an area. At the very least, I may be able to populate the london forward operating base with certain war assets.

It's not a given that I'll be able to, but its the intention.

I'll PM you about them.

Yep.

As soon as the arms open, the crucible fires its bag of goodies all over the galaxy destroying the reapers. What that does is it gets rid of the magic carpet ride ride up to lala land. It gets rid of the thing that takes the form of a human child. It gets rid of the comment, "you do no know them, and there's not enough time to explain. It gets rid of the comment, "synthesis is the final evolution of all life". It gets rid of the pull this, shoot that and jump into this endings.

Or, it could do this instead. It fires its bag of goodies, but instead of destroying the reapers, it some how changes the reapers programming causing them to stop the harvest. A few moments later, they are seen flying back to darkspace never to be seen again. What that does is it leave them as a mystery of why they did what they did. It could also be something to investigate for a sequel to find out why they did what they did.

I have posted the above several times before.

This is how Renegade is supposed to be.

Would this also destroy the geth and EDI? In a scenario without Control and Synthesis, I would like some other way of (optionally) saving the non-Reaper synthetics.

You complete me. Well said.

I have no problems with non Cerberus personal within ME2 but I was thinking right now that ME2 due to it is a Cerberus focused game, that more Cerberus personal of all stripes as playable characters similar how Miranda and Jacob are.

I love Kasumi Goto and all non Cerberus personal and I can see why they have their fans. For example, from my dreams, Shay'la, a perky red head Cerberus Phantom that will mixes (both alcholic and non alcholic) drinks at the bar for you and all crewmates. A Capable biotic, she does favor the SMGs but she has a good knowledge of weapons of all stripes while being accuracy with them all.

Having Ashley in ME2. Because of potentially very interesting encounters with Jack. Conflicts about attitude and worldview that may infuriate both. Possibly character growth involved. I imagine that to be more interesting than the Miranda vs. Jack theme, who are basically just enemies.

From what I understand based on cut content, the original intention for the ending was a "suicide mission" system that would determine how damaged the crucible got and whether or not Shepard was bleeding out by the time he made it to the Citadel. I'm guessing it was a time thing as most of that got condensed into what we have now.

Its a widespread issue in developing triple-A games. The gaming industry has this notion we need to churn out video games as often as Hollywood movies so we see big titles get 1-2 years of actual development time while additional years are added when there's a change in the gaming engine. Andromeda is a good example of what could have been had there been an additional year or two of dev-time.

And of course, even though it gets brought up too often, Witcher 3, Witcher 3, Witcher 3. It's a prime example of what you can get if the devs take their time. 

I wish Mass Effect 3's companions rotated. You keep a core few (like James and EDI), but you get other characters for a few missions, or maybe just one, and then they depart.

Example: Kirrahe could be your party member during the Sur'Kesh mission, and maybe if you get another one later on a colony world, he comes back. You can then make the missions longer (and harder) and give that on-mission character techniques that respond to the enemies you'll be fighting. It gives an excuse to make the game challenging, as you'll have the tools, just wondering whether or not you can work with them.

Side missions should be epic in scale. Let's go to Dekunna and save some elcor, bringing along one of my other party members. Let me choose between saving a squad of huge elcor "walking tanks" or a larger squad of civilians, including medical support and transports. Either option will give you something, so you can't reduce it to calculus. Sprinkle in a few of "save them both" only if you make the right decisions. Not all of them, just a few, maybe 25% at most. There's a sense of accomplishment in those, don't take it away. Plus, it reinforces ME's themes.

If you're going to make a "save them both", let me work really hard for it.

Bring me into the Illusive Man's web of crazy thought. Miranda would be an excellent vehicle to use this, or perhaps even a dark deal with Henry Lawson. Make his thoughts understandable and even believable. By the end, he was just a ranting paranoid lunatic. Let him have a victory we can see. Actually show him controlling husks, even using them to accomplish Cerberus goals.

The final battle should take place at the Crucible. That's where Cerberus strikes. They allowed it to be built (and even made sure it happened), but then want to seize it's power for themselves. It takes Shepard's epic team of people he's accumulated over the galaxy. And don't just say it "destroys" the Reapers. The Crucible is a pulse that travels through the mass relay network (so it can hit every galaxy) and overloads Reaper code. If enough specialists are obtained, the geth are not caught in this blast, as they've evolved differently.

Then, destroy the Reapers utterly by attaching mass effect drives to them and steering them directly into stars.
