BG: Enhanced is nothing more than a cheap-ass cash grab. You can buy BG for peanuts on GOG.com and download the bazillion mods that enhance its resolution, streamline gameplay, add more companions, toughen up the enemies, etc.
So cheap ass it isn't. BG was $9.99 for the longest of times, only recently did they decrease the price to $6.99. Which is still a lot for a 14 year old game. 'Enhancing' the resolution of BG might be possible, but in a very limited way only, the graphics are still very much 1998. BGE redid all the graphics, they look sharp again. As far as I know, most of the mods should work. $20 for all the improvements is reasonable, only $13 more then the 'classic' version. More importantly, they'll have an iPad version for only $9.99 which allows us to play with folks across all platforms (Windows/iPad/MacOS/Android eventually). I still have BG and expansion sitting on a shelf behind me, but I'll buy the iPad version...
This is going to be an actual NEW game inspired by the old IE games, created by some of the most talented people in the industry, without publisher-imposed deadlines and limitations - and you can have it for $20-$25. That's pretty damn amazing.
Assuming that Obsidian's short comings with their previous releases lies with the publishers might just be wishful thinking. Because Bioware could work well with Lucas Art for KotoR1, and KotoR2 was buggy as hell. Bioware made an excellent NWN1 series of releases, NWN2 was also a buggy mess. Remember Alpha Protocol, buggy mess. Dungeon Siege III's design direction might be due to decisions from Square Enix, but the lousy PC port (was essentially a console game) is squarely on Obsidian's shoulders. Fallout New Vegas is viewed by many as better then Fallout 3, but again a slew of technical issues.
Don't get me wrong, I own most of the Obsidian titles and those I don't own are on my wanted list (except the upcoming Southpark title). But blindly giving Obsidian money and hoping for the best, in a market which imho isn't all that lacking, is not what I'm going to do. I do understand people's desires that they can go back to the CRPG peaks of BG and PS:T, but honestly I think it'll fall short of the massive expectations.
I must note that I generally don't buy titles at full price, the last I did was Diablo 3 CE and that's the last time I'll do that. The one before that was SC2 CE. Most of the rest of the games are either budget titles and/or bought during Steam sales. So spending €20 for a game I'll have to wait for atleast 18+ months, have experienced issues with previous publisher titles, and (will) have enough of other CRPGs in that genre/style, is more then I spent on most titles.
Now, if they made BG3 I might have considered it. After the Planetary Annihilation intro for it's Kickstarter campaign I might have become spoiled ;-) I expect more work up front from a publisher like Obsidian. We have a map and an intro screen, and a update after $1.5M shows a dwarf concept. Call me disappointed and clueless...
I'm not saying folks shouldn't preorder, heck $25 for a new game is not bad at all! But please keep in mind that many good new titles are also indie priced, Torchlight II is only $20 for example. I'm just trying to point out some of the caveats concerning Obsidian and the project.
