I just finished "Brothers: A Tale of Two Sons" and I heartily recommend it. I've never purchased an indie game in my life, but this one came recommended to me by a friend and it received excellent reviews and several "Game of the Year" mentions. I bought it on a whim at the last Steam sale for a couple of bucks. As I've gotten older, I have much less time to play video games (unless it's something with the kids) so I can't invest in a 200 hour long saga like Skyrim. This one was only about 4 hours or so from beginning to end. But it's what's inside that counts, and the story told over those few hours is excellent.
In short, you use both analog sticks on a single controller to move both brothers around the screen at the same time. This allows you to solve puzzles and move along the game's path. I thought that the control sytem was pretty ingenious, really. You have to sort of train your brain to do two things at once. But it's certainly not a twitchy action game, so you can typically take your time to sort things out. The game is definitely story driven, but there isn't a single word of dialog that is in English (or any other known language, I believe - I think they just made up a language). That being said, you learn more in gestures and environments than you would with an omnipresent narrator. And you really get emotionally invested in the brothers you control.
A game like this is probably not going to be everyone's cup of tea, but I loved the story. It starts out fairly light-hearted, but things gradually darken. By the end, well... I am not going to spoil it. But if you're a bit bored by the same old video game cliches and want something a bit meatier, I strongly suggest this game.
Best of all, according to
this, the game is currently free for PS3 users. It's definitely worth a few bucks, and is a no-brainer for a free download.
