How did you manage to get a hold of them? How did you find them at all? I want to learn from you. :) There's lots of games that i want to track down their IP status.

It just so happens we have a thread devoted to this on GOG. ;)

To track down an IP, start with the original publisher and developer. Use resources like Mobygames and Wikipedia to identify those companies. Then, find out what happened to the companies. Generally, this kind of information is public. For U.S. companies, most states list the status of companies publicly, which you can find from the company's home state's Secretary of State site. France has an equivalent site, societe.com, I'm sure other countries have similar systems in place. If a company was closed due to bankruptcy, you'll have to find a way to get access to the court documents, but even then information on IP ownership isn't guaranteed. Older cases are generally not stored online, you'd have to order the records from the exact court or visit the courthouse in person, but you could at least get the case number and court name from pacer.gov (although you'll require a credit card to access the site, and every page visit costs money, but if you don't spend more than $30 worth of traffic on the site for about half a year you won't be charged). It's also possible the company was absorbed by another company. If the company was dissolved or worse, suspended, then you'll need to track down the employees and send them an email. Mobygames' credits section on individual game pages, old manuals, etc. are a good source to find names, and it's best to start with people at the top like project managers, producers, etc. The secretary of state sites usually also list the name of the agent of service of that business, and that was how I found who owned Strife, but the real problem was getting in touch with them. I eventually did that by identifying, tracking down, and getting in touch with some of his colleagues, who forwarded my emails to him.

Cool, tahnk you, does that mean that the other games that Velocity published have been found too? I think Velocity published some flight sims besides strife.

I don't know what else they have from Velocity, the Jetfighter series (some of the games were published by Velocity) are with Take Two Interactive for some time, I think.

It's a common issue with classic games released on Steam : no attention whatsoever towards ensuring a satisfactory gaming experience. Do they bet on enough customers bllindly buying the game ? Given the order of Magnitude of Steam's user base, this kind of cynical bet would be a good way to grab a good cashflow from their IPs while investing very little in it.

Strife pretty much confirmed:

Were you responsible for this release? I dont see Strife on greenlight, how is the game coming to steam without going thru it?

Greenlight is for games without publishers. Since Night Dive will publish the game on Steam, there is no need for Greenlight.

Strife as a Steam exclusive would be hella depressing.

Most of the doom ports support Strife, they are more or less just going to sell the WADs that everyone is able to use with them.

So that's a yes? I don't remember if there ever was a free mouselook mod for Doom since I played them with only a keyboard. Didn't feel the need for a mouse with the Doom games.

You dont play doom with a mouse, but want mouselook in strife? I think zdoom which supports strife has mouselook. Gzdoom too. They both have the most options.

Thank you for the tip.

Yeah I want it in Strife. As I said above it's because of the maps. There are some tricky maps in Strife that would be easier with mouse look. :)

There's some more teasing:

Those screens are from Strife, so it looks like the release may be using an enhanced engine with mouselook already implemented.
