Overwatch comes out on Tuesday, and the hype train is rolling.. This is the first new IP Blizzard has released in
17 years, their first FPS EVER, and it's drymounting incredible. 9.7 million people played the beta. if you're a fan of Blizzard, Team Fortress 2, arena shooters, class-based FPS, objective-heavy team FPS, you really need to check it out. The game is seriously impressive and Blizz did an AMAZING job. They perfected the TF2 formula, imo.
Here's a really well done video series about the development story, ton of insight from Jeff Kaplan and Chris Metzen. Second part is my favorite, you'll love it if you played games like Quake, TFC, HL:DM, Counter Strike, etc.
If you're on the fence about Overwatch, you'll have made up your mind after watching these.
