The Games Industry is possibly looking at a crash soon, which could have a big impact on the tech industry as well.
AAA game development costs are booming to ridiculous highs and the games aren't delivering. The last Tomb Raider reboot sold over four million copies and failed to break even. It's getting difficult to survive at the top end and the middle ground can't compete on marketing.
The only sector that's doing well is indie, where the budgets are low enough that people can turn a profit, but even that area is hitting a problem: saturation. The low entry level is leading to too many developers making too many gamers. Suddenly being an indie is about marketing and there's very few people that can afford that.
