I didn't get into GO (although might give it another shot for the Battle Royale ridiculousness). But I was a fiend for 1.6 and CS:S back in the day! Start building a friends list, and find people to play with. You can play it solo and have fun, I certainly do, but finding people to party up with is awesome.
I've been holding off for ages until I saw this. Used to play counter strike and team fortress 2, until they both became a jumbled mess of collectible tat. Bought this deal though.
The World could always use more heroes! I sit here in my Tracer from Overwatch t-shirt, wishing I was playing Overwatch, while building a Ryzen rig out of second-hand parts on which to play more Overwatch. I bloomin' love Overwatch. I love playing it. But I also love watching it, and am hyped for Season 2 of Overwatch League in six weeks time. (Our London Spitfire won the first season! #AcesHigh) It's smart, it's fun, it's gorgeous, and it's got one of the best communities on PC. It'll run on almost anything faster than a potato. I started playing it at launch (no pre-order) on a cobbled together AMD-based system with a CPU from 2011. If you're on the fence, wait for a free weekend.
That would flood the game with even more smurfs. I'm sorry, but I don't see any reason for Blizzard to make this free to play? :/ or they could invent some sort of access pass like WoW has. That I could imagine happening.
