1st Place: Life is Strange - SHOCKING NEWS. Life is Strange isn't perfect. Far from it. It's got some pretty big flaws really. The dialogue can be rather dodgy at times, sounding very much like the product of middle aged Frenchmen, rather than authentic teen dialogue from the Pacific Northwest. Graphically there's not a lot to cheer about, though the art style is nice, and some of the facial animations can be lacking. As for the ending, well that's polarising at best (though the people saying it's as bad as Mass Effect 3's ending are straight up delusional).
But you know what. That doesn't matter. Because what Life is Strange gets right it gets so right that it becomes 2015's most essential game. It may hit story beats from movies like Donnie Darko, The Breakfast Club and The Butterfly Effect, but those movies are awesome, and Life is Strange feels like a cult indie movie in video game form. The focus on characters and interactions with them is a wonderful touch, and I loved every single one of them. The moments of stillness where you get to pause and reflect on what's going on, or lie in bed with your best friend listening to a track on the stereo, were some of the best moments of gaming in 2015 for me. Stillness is incredibly underused, and actually having the chance to pause and reflect on events was a revelation.
Life is Strange is about the characters. It's about visiting Kate Marsh in her room. Twice. It's about going for a swim with Chloe, then pressing a button next to Chloe's bed. It's about dealing with Warren, and dealing with the cool kids in their oh so cool clique and finding out that beneath the initial impressions, there might just be something more there to uncover. It's about the bullshit of teen drama feeling like the most important thing in the world, and how that affects them when suddenly it is the most important thing in the world. It's about domestic violence, bullying, social exclusion and loss. It's about real issues and by focusing on those and seeing what they did to characters I felt emotionally attached to (thanks to great performances, especially from Ashly Burch), it left me a completely broken wreck on multiple occasions.
It's the most human game I've played in years, and is my favourite game of 2015.
