I agree both are games with the left modern and the right probably Old English game.
Gaming birds were bred originally for cock fighting, or gaming, back in the older days (1700-1800's) but fell out of fashion as more and more precincts outlawed gaming due to the destruction of birds in the fighting process.
Games are bred now for show and for pet quality.
Depending upon the line and breed, the males can retain fierce aggression towards other males, and some game cocks have to be tethered so that they are not constantly fighting other males.
Overall games tend to be flighty, especially the Old English, and can be quite good at hopping the fence or bolting over the lower trees, so netting may be in order.
Most games do not carry enough body weight to be useful as a meat bird, unless it is something like the Old Cornish Game which is a significant meat bird.
The females tend be good broodies and mothers (like to sit and hatch eggs and raise chicks) so a number of people will keep some game hens for the sole purpose of hatching chicks.
The one thing games overall are typically not good at is laying eggs. The eggs tend to be small and fairly infrequent especially compared to the prolific layers such as the commercial Leghorn, Sexlinks, and Rhode Island Reds.
Fun backyard birds that add a lot of "eye candy" and personality to the flock as long as you take into consideration their unique traits.
