Opinion: Best overall system for GUN games?

[Captain Wrong]

I recommend a ps2. You can also play the ps1 gun games too. Heres a list.

Ps1

Time Crisis (Awesome!)
Time Crisis Project Titan (Awesome!)
Point Blank 1 2 3 (Very Strange games...but good)
Elemental Gearbolt (Dude, seriously, talk about hard..)
Lethal Enforcers 1&2
Die Hard Trilogy

Ps2

Time Crisis II
Time Crisis 3 ( haven't had a chance to play yet)
Vampire Night (Pretty challenging gameplay, and a complete one is kinda hard to find.)
Time Crisis Crisis Zone( Its okay, don't pay too much for this)
Ninja Assault( its okay, ninjas with guns is kinda strange)

I'm not sure, but I think Dino Stalker and Resident Evil Dead Aim are light gun shooters too.

Yep.

And Dino Stalker and RE: Dead Aim are light gun games.

There are actually a few more PSX gun games, Area 51, Crypt Killer, Project Horned Owl come to mind.
