Just a thought and some optimism for what could come next

First off, I am not a fan of the ending. I thought it was nonsensical and counter to everything that came before it. That said, I had a thought on what could come next for the galaxy. Since the relays exploded everyone's first thought "well there goes galactic civilization and prosperity." And that's a reasonable assumption, but as we've been told new relays will be built with non-Reaper technology(obviously this should have been in the game at launch and just shows that Bioware got lazy, but I digress). This could mean a new system entirely, one that doesn't act as a tunnel system and acts more like a slingshot, sending you wherever you desire instead of just systems with relays built by someone else.
So what am I getting at? More. More systems to explore, more alien races, more new kinds of tech, more everything. Think of the possibilities. Imagine a galaxy of endless discovery and wonder.
Just my idea. It made me a little optimistic to think of the possibilities.
