I have paid, and they've had my money since last year. I may only have 30 posts, but I have been reading these forums for awhile before I even had an account, and once I created an account I didn't post but occasionally, and not more often till recently when I got out of school and had more free time to check forums and such. And so no, I havn't been asleep for years. I've been playing with the free version of TG for awhile, then played a bit with TP2 when it came out free version. It wasn't until last year I felt like buying it since release was near (well, as of then it was), but when it didn't come out I felt a little bummed but not betrayed. But I can understand how its currently going with the project. As I said first 90% is easy, last 10% is hard. Many companies release gold with so many bugs because they get pressured by users or they just have crappy programmers. Then you spend the year getting the other 10% in bug fix updates. However, PS is showing they are trying to be 100% when they complete so updates can be content, not just bug fixes. And their decision to support multithreading is one I support since it helps ALOT.
If you want a "gold" so bad I'm sure yes, they could rush one out the door probably today. But it would be a crappy gold with bugs still in it. Or you can wait, and get to see a real gold release.
I think the main problem is PS wanted to keep adding features and probably should've just frozen earlier. But the decision to do multithreading was probably the biggest pushing back of the release, and thats easy to see. But the fact its there makes TG2 soo much better.
And i know you guys have shelled out cash, so have i. and personally i dont see it as a huge amount considering what you get for what you paid for. TP2 and TP3 are quite impressive, and will hold me over just fine for the money i paid for. Hell, im a college student, and i managed to save it up and buy terragen at $200 bucks, and i was fine with that. It only took me like a weeks pay. it wasn't until recently i found out there was a student discount, which PS kindly gave me when I asked if I could have it.
And i believe you should be entitled to a refund, but don't expect to get a discounted price when tg2 does finally release.
