That's just.....that's just not how this stuff works m8. By and large no, "video game workers" are not gig/contract most of the time. It does happen, especially at lower levels; but it's foolish to believe anywhere close to the majority of layoffs come from contracts. Those often have built in buy-outs anyways - this is talking about the full time artists/staff/programers who are always working on something
You don't honestly think Infinity Ward laid people off after not getting the contract for Call of Duty: Black Ops (2010) following Call of Duty: Modern Warfare 2 (2009) do you? Or consider the time between Naughty Dog's Crash Team Racing (1999) and Jak and Daxter: The Precursor Legacy (2001) - That's two years. Two years without releasing a game, yet they didn't lay anyone off?
Buddy, there is always a next project. Project Managers will fill every single artist's calendar of deliverables for supporting the current game (someone has to make DLC, though it is sometimes outsourced) and any future projects. They also do buy assets and employ contract work in these domains, but again, it's small in the grand scheme of things.
Programmers will always be optimizing the engine, working on patches for an updated build, or again working on the next game because every business worth it's salt isn't going to fire experienced staff in preparation for the next project as demanded by the need for more returns
Unless other economic factors change - a company may choose to engage short term solutions to keep profits looking healthy. If it's cheaper to lay people off then it is to compete on merit (make a new game) why would you from a business perspective?
These companies are run by bean counters; not artists and devs anymore. Almost every game company was started by people who wanted to make good games, and now these same companies are laying people off regardless of their position in the market.
Idk. Games come out way too frequently to support the idea that these people are getting laid off in between projects. It doesn't add up. These layoffs are very recent in the grand scheme of the game industry.
You probably wouldn't make a great candidate in a security focused knowledge domain. It's pretty evident you don't understand risk.
