There's still time to submit your favourite developer lists, if you want to ensure your favourite devs are included in the tournament. Just post your list here.

i believe either insomniac rare or guerilla should have been put in round 3 this round is way to over clocked :(

I feel the opposite, i like none of them. Probably wont even vote, to keep it fair.

I went with Insomniac. Another set of great choices, but I cannot deny my love of Ratchet And Clank. A Crack In Time is one of my favorites from last gen. I just played through and platted the 2016 remake and Into The Nexus this past summer. I had great fun with Resistance 1 and 2 as well, which were actually the first Insomniac games I ever played. Still have yet to experience anything from their PS2 catalog.

ID software deserves this one. Doom, wolfenstein and so many other great games over the years. Can't wait for Doom Eternal, it looks like even more of the fun from 2016.

Man, I don't know why but I still voted for Rare ... I mean pre-modern Rare.

Probably would've voted for ID Software or Good-Feel (I do think they might struck gold with Yoshi's Crafted World) otherwise .

The total of votes stumbled in the last round, which might mean the 2nd round had some outsider's influence for the vote of a certain studio ...

Voted for Insomniac, the Ratchet games are just sooooo fun and the quality of their output has been so consistent through the years (haven't played Spider-Man but it looks really fun).

Rare will most probably win because of their old SNES/N64 stuff tho.

I can't vote for any of these games, which is very Rare, because I am an Insomniac and stay up all night playing games to make me have a Good-Feel. It doesn't matter if the game is about Guerrilla warfare or Bungie jumping, every Molecule in my body is made to love and enjoy games. In fact in my Cavedog room I have a wide assortment of games stashed away in my Gearbox. This may be a Paradox; me loving games yet not being able to vote in a round of some legendary developers. If I had more time, maybe id be able to vote. 

is this bait? it didn't work

While Paradox games are awfully similar to each other and hard to get into, I love them a lot and have played them for so many hours. They will get my vote.
