Great Genre / Theme combination in Game Studio Tycoon 3 [closed]

I would like to know what are the other great combinations in Game Studio Tycoon 3. I already have done these types of game combinations, and listed are the effective ones:

• MOBA/RPG - ACTION/FIGHTING
• STEALTH - ACTION
• RACING - REALISTIC/ACTION

These are my combinations that works great but I would like to know the others.

Update: Once you already made a combination like that, even if it is 10 years ago it still decrease the rating and I don't know why.

These two are easily the best they work every time.

RPG/SHOOTER - ACTION/ADVENTURE

RGP - FANTASY/ADVENTURE

Shoot/Moba war/sci fi is a good one

Simulation/Shooter Scifi/Futuristic always gives me 8.+ Stealth/Shooter Action/War is a good one too
