I definitely agree with the OP (brentrobison) on pretty much all of his points. I don't think Sins needs a drastic overhaul or anything from the devs or even modders, but I think some additions or tweaking could help make this game even better than it already is.
That scenario that brentrobison was describing, that WOULD make the game so much better, more DRAMATIC, thrilling, exciting, and unexpected. I don't know about anyone else, but surprises in games are SOMEtimes the best part, if not all the time, even if the surprise is a nasty one. Surprise creates tension, and also adds ANOTHER reason for someone to keep playing the game, just like cliffhangers or plot twists in movies, books, and the like.
Whatever, I'm rambling on about all that. I do agree though, more, bigger tech options and increased defense effectiveness would add a lot to this already amazing game. A greater number and bigger variety of tech would give the player a lot more decisions and make the decisions much more important, such as "Do I completely focus on making lots of units and worry about upgrading later" vs. "Should I get all my tech and units at their maximum levels so I won't need as many to do what I need to do?" or even a balance between the two. Right now, it seems like for the most part, if you have enough resources to buld a lot of ships, you have enough to do a lot of research. Maybe I'm imagining it, but I dunno, I think a greater divide between the two should be made to make players think more.
And yeah, planetary defense....I think the defenses are OK right now. I've seen my cannons and fighter bays do a pretty good job of fending off attackers, but I agree again with the OP, a fully tech'ed, *ultra* planet should be bristling with defenses and a real challenge to face. I don't know if anyone can relate, but in the Halo universe, there's Earth and Reach with their massive plantery defenses, which make it a bit of a challenge for attackers to win battles, even the Covenant. And thinking of how there are "SIEGE" frigates, thats what I think an attack on a planet should be, a siege. The defenders SHOULD have some big advantages with their developed planets!
--My point I guess is that defense is OK for now, but it should be changed a bit to improve the gameplay/atmosphere/strategy/variety of options for player.
I've talked long enough, been a bit of a nerd, whatever. I'm not expecting every little expectation of mine or of anyone's to be fully met by the devs, thats not their job at all, but I'm hoping a few improvements will be made. I kinda know there will be some actually, cause the devs have already been doing so.
