I read your post in the "News" section about where you think PoL should be headed. Here are some thoughts.
I've been a gamer since the PC came out. I used to love to manage my DOS environment to get a game to play just right and maximize it. Those days are long gone though, and when Windows gaming started to take over, the environment got a lot simpler, and the games got better. Then, somewhere along the way, Microsoft became evil. They got too big and started doing things that just didn't make sense, using the OS to manipulate the market in various products. About that time, little o'l Linux started popping up more and more.
I made the plung somewhere in the early 2000's, having used Redhat 4.x at work. Back then, I had to dual boot Windows and Linux. Little by little, everything I did moved to the Linux box, except gaming. No matter what I did, I couldn't get a stable platform on Linux to support gaming, while my Windows build was always stable and played everything I had and wanted. I eventually settled into a mode of having a high end gaming system running Windows, and a lower end system runing Linux. When I built a new gaming computer, my old one would become my Linux box. I've been runing that way for years now.
So this weekend, I decided to see how well my Gaming computer could handle Linux, and just what I could get running. My games of choice these days are World of Tanks, Star Conflict, Star Citizen, Elite: Dangerous, Lord of the Rings Online, and to top off my Steam setup, Wasteland 2. I used an old hard drive for Linux and swapped my windows drive out for safe keeping.
Sad to say, it has not been a very productive weekend. On the positive side, Wasteland 2, running in Steam, ran perfect. I was able to get Star Conflict to work in Steam, and even figured out how to export my Steam environment so I could log into Star Conflict without having to use a Steam account. This was all better than I'd managed to get before, though I used to be able to get LotRO to run on Wine very easily. Sadly, that broke a few years back and I haven't had much luck since moving to 64 bit.
I always downloaded Wine from the site and compiled it from source. When everything was 32 bit, it always was pretty easy. Since it moved to 64 bit however, I've had a lot of trouble getting anything to compile and run and get a stable build. I tried downloading from Mint repositories though, and installed 1.6.2, what they had. I tried to run a few programs, but nothing really worked.
So then I loaded up PoL. This was the first time I had tried to use PoL and when I took a look at it, I thought, man, this looks great! I chose the script for World of Tanks, ran it, was able to pick the latest Wine version, everything installed, and then I'm looking at the play button. I hit the play button, log in, watch the status messages start to display... and then it crashed. Came here, signed up, did some looking, and yep, bugged (I think this is more of a Wine problem though than a POL, but I've posted it here). I tried a few other games that I play, but couldn't get anything to run, either in PoL or by exporting Steam environment or by runing with native wine.
I think I'm getting old. I used to love to tinker with this stuff, but now, I just want it to work. The biggest problem with gaming in Linux has always been getting a stable platform. I'm hoping Steam will take care of that, but I also don't want everything to be done in Steam, or else they'll just turn out to be another Microsoft. They need some competition. PoL could be that check on the system. Even though it's still another system I have to learn (I'm an engineer btw with a good background in programming), I think PoL is still worth something. The native Linux gaming environment if you try to keep a multipurpose desktop system, is difficult to maintain. PoL gives us something beyond Steam to manage and try to stabilize the environment, and that's important. I like how you've kind of taken the virtual machine concept and integrated it into your interface. I think it needs to be clearer as there are some pretty confusing aspects to it, but it's a good start and has a lot of potential.
What I have seen in the industry though, is that cross-platform is very big right now. Native Linux clients are coming out all the time, and that's great. But let me point out the dark side. Linux is great at breaking things. All it takes is one developer somewhere to change a library, and your whole gaming library is broken. Right now, POL is focused on Wine, but let me give you another area to focus in if you think Wine might be losing it's "Steam" (pardon the pun). If you could extend PoL to the environment, capture the libraries that are working, extend PoL into a kind of virtual machine, but just focusing on the environment and less on the kernel, you might help stabilize the gaming market some. I would think something that you could capture all the libraries a game is using when it's working correctly and just maintaing that environment so that if someone changes something in the main system, the game would still run, that would be huge. It's still tricky, and you'd still need someway to upgrade the libraries safely, but it's something to think about. I think you've moved in that direction right now, so you're kind of setup for it.
So whether you decide to keep going or not, thanks for at least taking it this far. I can see that you've put a tremendouse amount of work into this. Best of luck to you and your team.
