Reading through all this prompted me to add an ohbytheway.
People posting complaints here seem to fall into three categories:
1. People who cannot play the game due to stability/compatibility/hardware issues which may indicate that the game was not yet optimized for their particular platform combination.
2. People who can for the most part play the game and have gripes about gameplay issues, AI, UI, balance, programming glitches, unimplemented features, etc.
3. People who have suggestions on how to improve the game with additions/changes/mods.
Some of course are a combination of these. In my earlier post I was more or less in groups 2 & 3.
Here's my suggestion: Tackle the game's problems in the same order: 1, 2, 3. First get everybody able to launch and play the game consistently, no matter what their platform and hardware. Second, deal with the game's bugs and glitches, including AI and similar issues and non-working features. Finally, work on adding the neat stuff and making changes that people want just to make the game cooler.
If you spread your programming resources out too much trying to tackle all three issues simultaneously, I fear that too many people in category 1 will suffer at the expense of those in 2 & 3. Group 1 paid for a working game and deserve it.
If you have the means to split programming resources, I'd suggest something like an 80%/15%/5% spread of them over these three categories, at least until the majority of #1's issues have been mostly dealt with. I'd think that the goal is that 95-98% of all game purchasers should be able to play the game if their rigs are reasonably mainstream. The 2% to 5% that can't play a stable game after all you do, may have their own rig issues including OS, BIOS, drivers, etc which they have a role in fixing too. Give them some good leads based upon analysis of their failure logs.
I really want the game to succeed and want all my fixes & changes addressed some day, but to be fair, since my game basically works now, I do not want to get my less urgent needs met at the expense of those purchasers who can't presently play what they paid for. I can be patient but they may not be able to be much longer.
