So far its seems for the price of aimtrack gun its not really worth to play gun games. Does anyone have a good list of games that are worth to play personally. these are the one i know
1. area 51- MAME
2. duck hunt- NES
That's not much of a list.

Whether it is worth it or not depends on how much you like gun games.
Download the AIM-Trak setup guide just above the picture of the board.
http://www.ultimarc.com/aimtrak.htmlAll MAME gun games are listed there.
Then you have the PC version of the American Laser arcade games from Digital Leisure:

Nebulas Model 2 emulator plays House of the Dead, Virtual Cop 1 & 2, Behind Enemy Lines, Gunblade NY, & Rail Chase 2.
(but only 1 player)
Demul plays a half dozen or so including Maze of Kings & House of the Dead 2 if you have a fast PC (don't remember the rest).
(again, 1 player only and integration into a front end can be a PITA)
There are also a bunch of online flash games, but I've never messed with them.
I've been using old Act Labs ray guns for the past year.
I bought an AIM-Trak & a happ recoil gun to install it in, but haven't had time to work on it yet.
If only I could do it at work instead of just hanging out on BYOAC all day.
