Apologizes for not getting back to you in a timely manner - I didn't see your message yesterday until I needed to get ready for bed. I'll try and answer them as best I can.
Thanks for pointing out the note on the game's Steam store page! That's definitely something concrete to put in the key points section as it's factual information about the technical side of the game, but given the vagueness of the dev's note, it's not really useful as far as PCGamingWiki is concerned. I'd paraphrase the developers themselves and provide a reference to that source. Either look at the sample article or create a sandbox page on your userpage so you can copy wiki articles (like the Earth 2160 article) and play around with and learn the formatting without worry. (As I don't have access to your global edit history, I don't know if you have enough edits to start creating your own pages on your own, so you may need to ask around on the IRC so a PCGamingWiki staff member can create your sandbox page for you.)
To give an example of paraphrasing the devs in a way which is detailed yet short, you could do something like this (without the quotation marks):
"Game works well under Crossover for Mac or Ubuntu 14.04 or later with the latest NVIDIA drivers and at least Wine 1.6."
Since the sample article, while official, is out of date, I'd recommend you look through the work-in-progress wiki article guide by PCGamingWiki staff member ThatOneReaper. Besides actually giving lots of examples and rationale for how articles are to be written and formatted, I don't think ThatOneReaper's had very many - if any - new users look through the guide; any input you could give in the article's feedback forum thread would be greatly appreciated!
The AppID for a game on WineHQ is found at the very end of the URL for a game's profile on the WineHQ AppDB. For example, the link to EVE Online's AppDB profile looks like this:
The number at the very end, 2249, is the AppID number; the part of the URL which says Class=application indicates this is the application's actual profile, and not a sub-page. If the URL doesn't contain that text, then the AppID number won't bring you to the correct page.
This works similarly for Steam games, too. To use the URL for Exanima's Steam Store page as an example:
The number at the end, 362490, is the game's Steam ID number. Thankfully, everything sold on the Steam Store has a unique ID number - and that includes DLC - so as long as you're on a game or DLC's Steam Store page, just look for the number in the page's URL, and you've got what you need!
Also, if you think you'd like to try using Linux, and if you have a PC with Windows on it, at least 250GB of spare hard drive space on one of your PC's hard drives, and have something to backup all your important files onto, such as an external USB 3.0 hard drive or a 32GB+ flash drive, I'd recommend installing the latest (non-LTS) version of Ubuntu. Why Ubuntu and not, say, SteamOS? Here's five good reasons:
- Ubuntu won't automatically wipe all your hard drives just so it can install itself on the first one it sees.
- With some preperations beforehand, Ubuntu can be made to peacefully co-exist alongside Windows.
- Ubuntu is more like Windows, so installing things other than Steam games is much easier.
- Ubuntu has the most free online tutorials designed for first-time Linux users, so you'll usually be able to figure out how to do stuff through a simple Google search on any device.
- Provided you're not installing Ubuntu on a laptop with two graphics cards (such as Intel and NVIDIA or Intel and AMD), all it takes to get Steam working on Ubuntu is the official Linux Steam client installer and the latest Linux drivers from your GPU manufacturer.
