Ok, it looks fine now. I would only add two more links:
as an addition or replacement for the official product page. The packs can easily be found from there.
is the Postal 2: Share The pain version distributed by LGP.
I agree with you, Collection should be replaced with Requiem. I consider another valid option removing "Overture" and "Black Plague" from the database. The full Collection is now the only available purchase in the official store.
Looks like sixsixfive decided to replace Postal 2 Multiplayer with Postal 2 and mentioned Multiplayer and Apocalypse Weekend within the description.
Game: Dead Cyborg
Browser version (with Linux support) is released: http://deadcyborg.com/playinbrowser.html
However, it requires Burster plugin (which allows running Blender Game Engine based games in browser): http://geta3d.com/index.php?option=com_content&view=article&id=9&Itemid=9
Unfortunately, at the moment it is available only for RPM based systems (it is said that *.deb will be also available soon); if you want to run it under Debian based systems you will need to manually extract files from *.rpm package and install them.
> The last two are mods developed by Resurrection-Studios.
If they run under Linux, it's ok to add them, just mention that they need original game to play in description (and add Total Conversion tag, if required).
> Do you think they should be also included or is redundant?
I think the packs (as separate entries) will be redundant. Instead, for every game that is available in pack you could mention it in the description/comment and provide additional link for that pack.
> When searching for examples of packs in the database, I found the "Penumbra: Collection"...
IMO, Collection should be replaced with Requiem, and then information/links about Collection should be mentioned for every game in series.
> Please, note that "Overture" and "Black Plague" miss the developer information.
> Postal 3 will be released for Linux
Yes, as far as I know devs had promised the Linux version. Let's hope that nothing goes wrong and it will be released.
if its an add-on like requiem for the penumbra series, it should be mentioned in the description and not added separately.
if its a total conversion it should be added separately.
Postal 3 will be released for Linux
