Silent Scope is one of those games that consoles still can't touch.
Agreed, same with Big Buck Hunter, or even a game like Golden Tee (which I still love). Silent Scope was probably my favorite arcade game I ever played...time crisis games were really fun too (and I haven't seen a good replica on a home console/system).
I suppose you could even say games that have a motorcycle type of thing you sit on and race (and lean side to side) aren't easily replicable on a console, but that's not really my cup of tea (nor do I think they are really that great).
