Space combat is optional, but it IS there. It's cool, kind of reminds me of Lylat Wars. Which is a good thing.
I like the way Bioware haven't been scarce with their mailbox placing, props to them for that, but i agree i dont see the point of them. Instead i see your ship being used as a massive hub for you.
Why does GTN even exist within the respective 'home' base? you could slap whatever you wanted in auction all from your ship? Maybe that is too lazy, and it doesn't really promote massively multiplayer if everyone does everything from a reclusive place. But it's a thought.
The fact that you can engage in space battles is an awesome addition, and one i didn't expect, or look forward to.
I love having my own ship, i just feel like they could do so much more with it - and i hope they do! A friend suggested a co-op space battle scenario, which could be amazing if done correctly. A wingman if you like.
Incase you were wondering, yes i do play the ACTUAL game too .
