Even if there are problems, as long as the problems aren't fundamental, they can be fixed, and Stardock's history says they will be fixed.
I'm no code monkey at all, my friends actually banned me from ever trying to code i was so incompetent. However, I could tell that Stardock was trying to make sure nothing unfixable was left in the game. That's why everything is so moddable- the side benefit is we get to play with the tools, but I think the main reason is to make sure the game can be improved over time, which helps repeat business.
Look at GC2. Over the course of the game, Stardock improved a lot of things, and made the game from decent to a near-classic (I think you guys fell short of classic, but still in the very good category, and I was more then satisfied with that). The only thing that kept it from being classic were some niggling things that couldn't be patched. (I think another XP would have made GC2 a classic if you had fixed the sliders and tech trading, which you guys did in this)
I do think the survey shows that many of us do think Elemental was rushed out the door earlier then it should have been. While I think Brad disagrees, it does show in some areas. That said, I think the hardcore Stardock fans will give Stardock a lot of rope, due to the respect that has been earned in the past, and patience will be shown- I do think Stardock's fans are much more patient then any other fans I've seen- because they get rewarded for it. I'm expecting decent at launch, with steady improvement for 2 years. I'm unsure if a true mod community will form though due to the updating. The big mod communities tend to happen in large games, or games that are good but with gameplay issues and not a lot of support for them (Total War games, AoW)
I know with Elemental, at worst I'll get a decent game at launch, and one that will improve over time, and an improving game is like getting the new game feel over and over to me. I hate saying this, but I'd rather have a good game become great at day 180, then the great game at day 1. I'll end up enjoying the delayed greatness more, even if that's irrational.
Gameplay, as long as it's numbers that can be tweaked and not the core engine- is easier to fix then other things. Core engine stuff will likely need an expansion, which I'm sure SD has a couple planned in the budget somewhere for mid 2011 and early 2012.
