Game Informer currently has a great little feature on their site, inviting 35 game developers to share their top 5 games of the generation just past. It is super interesting: both in terms of how varied it is, and in terms of the names that seem to pop up frequently.
Evan Well, Naughty Dog Co-President 1. Wii Sports Resort 2. Joe Danger 3. Limbo 4. Portal 2 5. Batman: Arkham Asylum
Ted Price, Insomniac Games President 1. The Elder Scrolls V: Skyrim 2. Uncharted 3: Drake's Deception 3. Journey 4. LittleBigPlanet 5. Limbo
Vince Zampella, Respawn CEO 1. Assassin's Creed II 2. Call of Duty: Modern Warfare 3. The Elder Scrolls V: Skyrim 4. Trials Evolution 5. Uncharted 2: Among Thieves
Randy Pitchford, Gearbox President 1. Super Mario Galaxy (Series) 2. Ni No Kuni: Wrath of the White Witch 3. Rock Band (series) 4. Viva Pinata 5. LittleBigPlanet (series)
I've posted a few of them above, but I genuinely recommend clicking through to check them all out. It's fascinating to see who chose what. I was surprised by how many chose Limbo -- a game that I loved, but I'm not sure it's anywhere close to my top 5. I was also surprised by how few people chose Dark Souls -- a game that I assumed would be popular among developers.
Personally, it was really cool to see Vince Zampella chose Trials Evolution. It's a weird game to have in your top 5, but it would most definitely make mine. Also Tommy Refenes from Team Meat made Metal Gear Solid 4 his number one. That's a brave choice, but it would also make my personal top 5.
