A possible improvement for the website would be adding statistics and detailed list of games with graphs, something in line with the games sales but for all games. More in details:

A table listing all existing linux games with the following columns:
- title
- a small image
- genre
- Metascore
- release date
- distribution (developers webpage, steam, desura...)
- price: dynamic, could be the lowest price in the last month or something else
- official page link
- link to GOL review page written by GOL users, otherwise a link to metascore should be sufficient.
- GOLScore: writing a review is time consuming but a "survey" with a few "1 to 10" question (graphics? fun? hours of play? sound effect? sound track? how easy to install? stability? bugs? support? devs communication? is it my favorite genre?...) could give a good idea of the game without much effort. Eventually a single-number-GOLScore derived by the survey would be more meaningful for linux games than metascore because the latter is intrinsically a comparison of windows games.
- a report sale button

Table of games in development:
as previous table but with crowdfunding details where applicable

Graphs:
Graphs are easy and fast to read and they attract people especially if they are updated regularly (thinking about steam stats).
- games released by month (histogram, x:month, y:#games_release_that_month)
- quality of games released by month (game weight based on Metascore or GOLScore): a user, comparing this graph to previous graph, could immediately tell if on a specific month the quality of games has been higher or lower than usual
- games released in total (line x:month, y:#games)
- games released in total with platform comparison like the graph in the recent Valve presentation (with a note about log scale ;) ). This is possible only when the total number of games per platform is available (i.e. steam)

Other statistics:
- distributions used by GOL users

Collecting data:
it should be the most automatic possible. For example last night I wrote a program to check if there are new games (including names) on steam without me having to scan the list and find what has been added.
If it needs human intervention it should be a distributed workload among a set of trusted users to keep it as light as possible on each user. It wouldn't important to have a specific user online but the number should be tuned so there will always be some user uploading data with maybe some redundancy for validation.
