thatgamecompany is an incredible development studio, that looks at game design differently. Sony is a wonderful company for supporting developers and games such as these.
Here's the bonuses that the game includes, aside from the 3 games (flOW, Flower and Journey)
*Thirty-minute behind-the-scenes documentary about the making of Journey
*Creator Commentary playthroughs of all three games
*Three exclusive mini-games from thatgamecompany
*Concept art and screenshot galleries for all three games
*Original soundtracks for all three games
*PS3 dynamic themes and wallpapers
*PSN avatars including eight exclusive new Journey avatars never released before
*Official game trailers and developer diary videos
*Reversible cover art
flOw is great, though their 'worst' game. That's not saying much, because it's still a good game. The tilt controls can get a bit wonky at times though. Once you get used to it though, you're good to go. You basically play as an organism, going through it's evolutionary process. It sounds weird, and it is a bit. You eat other organisms and grow. That's about all there is to it, going through 'layers' (sortof levels) until you unlock a new 'class' of organism to play through it's life.
The art design is incredible, the game has a screenshot feature for a reason.
Flower, my favorite of the 3. You play as a pedal in the wind, gathering more pedals from flowers. You fly around using tilt, hitting any button to speed up. You hit a flower and a musical queue is played along with the INCREDIBLE music. It blends so well. When you bloom a flower, you gain another pedal.
As you bloom more and more flowers, the world becomes beautiful again.
There is no death, so you can just focus on the emotional journey that Flower is. It's hard to really explain this game, it's an experience that you just have to try for yourself. The emotional impact it had on me is unmatched by any game. It's art. No matter what people say about it. If you play it with an open mind, then you'll understand.
Journey, probably thatgamecompany's biggest success. It's incredible as well, and very close to Journey. The story of the world is magical and mysterious. You go through the world, collecting glyphs that extend your scarf. Which allow you to glide/fly further.
The online is innovative. You'll randomly be connected to other players (only one other at a time), going on their own Journey. You're able to follow them, or ditch them and do your own thing. And the online is so good, that you'll more than likely end the game thinking you've been through the game with one person. Only to see the names of multiple people you met on your Journey after the credits roll.
There's a lot of attachment to that other character when you go on a Journey together. The bravery they had to avoid any form of real world communication (voice, text, usernames while playing) really enhanced their overall game design and pushed the connection they wanted people to have with their companion to new heights.
The only form of communication you have is a 'call'. You can hold it for a different amount of time for different sounds. Calling near another Journey-er restores your scarfs 'energy'. Which allows you to fly. Through limitation comes creativity. People have to pay attention if they want to figure out what their new friend is trying to say. It's a lot of fun to communicate this way. It puts everyone on even ground.
