The oldest bought Rocket League with her Xmas money. Naturally I've played it for about 8 hours already. It's a ridiculously addictive game. Easily my favourite sports game. And probably my favourite sport, too!
It's got quite a steep learning curve, but once it clicks, it's fantastic. It eats away at hours like I do crisps. It's definitely a "just one more go" type of game. I was up till after midnight playing last night. On a school night!
