Results from round 9:

Bolded = proceeding to the next stage
Italicised = will get a second chance in the bonus round

I know it's heretical, considering the company's modern-day misadventures, but I can't overlook three decades of classics: Contra, Gradius, Castlevania, TMNT, Metal Gear, Silent Hill, Suikoden, etc. Konami it is.

Sega > Remedy > Platinum > Subset > Stardock > Konami

Sega- I was a Sega kid in the 90's, love alot of their series, Sonic, Shinobi, Panzer Dragoon, Nights, Phantasy Star, Shenmue, Yakuza, etc. Obvious number 1 choice for me this round.

Remedy- I really liked Quantum Break and Alan Wake was cool as well

Platinum- Nier Automata was awesome, MGR:R was awesome.

Subset- FTL was one of the coolest indie games I've ever seen.

Stardock- The Political Machine series is good fun, and watching some of my favorite youtubers play it has provided me with tons of enjoyment over the years.

Konami- Truth is, I have very little experience with Konami, I have only played Ground Zeroes from them, which was meh, but even considering that, I would still give them the lowest spot of the studios I am familiar with this round simply for cancelling the amazing looking Silent Hills game that Kojima and Del Toro were developing.

Sega! One of the easiest votes in this tournament.

Platinum Games, followed by Sega. 10 to 15 years ago Konami might have been in contention as well, but the way they are now there's no chance. The difference between Platinum and Sega is pretty much Nier: Automata, without that I would have probably voted for Sega thanks to Yakuza and Valkyria Chronicles.

Voted for Subset Games. There awesome.

This one's easy.

Frogger, Yie Ar Kung Fu, Super Cobra, Athletic Land, The Goonies, Penguin Adventure, Konami's Soccer, King's Valley, Road Fighter, Knightmare/Maze of Galious, TwinBee, Gradius/Nemesis/Salamander, Castlevania, Contra, Metal Gear, TMNT, PES, Suikoden and Silent Hill are some of the games/series I have fond memories of. Konami is my childhood.

You have to pick Inti Creates, people. For Zero.

Ah Sega, the greatest games they made back in the day.

Well, Remedy made Alan Wake, the best game ever, so... Yeah, I'm going with Remedy this round.
