Konami: make games again, and stop slave-laboring your employees.
Valve: learn to count to 3 and make Portal 3, Half-Life 3 and Left 4 Dead 3.
Sega: make Virtua Fighter 6, Sonic Adventure 3, make House of the Dead: Scarlet Down for PSVR, make Phantasy Star Online 3, make Alien: Isolation 2 for PSVR.
About all I can think of ATM.
