Can I use Classic on a G4 with Leopard?

Question

I have a bunch of old mid-90s games that I desperately would like to play on my newer G4 with 10.5.  It's my understanding from my searching that Macs ceased compatibility upon hitting Leopard, but I think people are using "Leopard" as a catch-all to describe not just 10.5, but G5 Intels too.
Apparently Tiger (G4 PowerPC) was compatible with Classic Environment, and that's what I have, I just use Leopard on it.
Semantics aside, I have an old G3 with 10.3 on it that lets me use Classic Environment to run OS 9 so I can play those old games and use Starcraft's StarEdit.  Thing is, it's a piece of crap next to my G4.
I do not have ANY of the Mac Installation discs for Classic (or any OS for that matter, so I can't use any of the emulators like SheepShaver and what-not), but is there some way to transfer OS 9 and Classic Environment from my G3 to G4 so I can play this stuff?
Is it even possible that they'd play with these things?

Hi, MasterDogma -
Just adding some info in correction -
I know Leopard doesn't come with Classic, and I know the difference between operating systems and computers, that's my whole point.
Not sure that's correct. When you said -
Apparently Tiger (G4 PowerPC) was compatible with Classic Environment, and that's what I have, I just use Leopard on it.
and
...but I think people are using "Leopard" as a catch-all to describe not just 10.5, but G5 Intels too.
it indcates you may not.
The terms "Tiger" and "Leopard" do not describe nor refer to any hardware or computer model. They are explicitly the names for different releases of the family of operating systems known as OS X: Jaguar = OS X 10.2; Panther = OS X 10.3; Tiger = OS X 10.4; Leopard = OS X 10.5; and Snow Leopard = OS X 10.6.
Just as important, there is no such thing as a G5 Intel machine. All Power Mac models, of which the G5 is one, use the PowerPC processor. When the Intel processor machines were released, the "G" designation ceased applying. For example, the Intel successor to the G5 desktop is called a Mac Pro; the Intel succssor to the PowerBook is the MacBook Pro.
It does get a little fuzzy with the iMacs, since the iMac designation was retained for the Intel machines - hence the common usage of references like i3 and i5 to differentiate the Intel machines from the earlier G5, G4, and G3 models all of which use the PowerPC series of processors.
