Glovepie, if you have time to learn how to use it, is in my opinion, vastly superior to Shoot! http://glovepie.org/glovepie.php It is too bad that the user agreement forbids using Glovepie for military simulators, as well as for anyone that live is Israel. Also, you must commit to using 100% green energy. from the Readme: "* You may not use this software directly or indirectly for any military purpose. This includes, but is not limited to, training, research and development, controlling military hardware, directing military personnel, or troop entertainment. You may not use this software anywhere on a military base or vessel. This applies to all versions of PIE. You may also not use it for playing “games” produced by the military to recruit players as real soldiers, including America’s Army. Sorry. * You may not export this software to Israel, or use it in Israel (including the occupied territories), until Israel has ended its occupation of the West Bank, Gaza Strip, Lebanon, Syria, and anywhere else it may occupy, or until Israel abolishes apartheid (granting all Jews and non-Jews in its territories equal rights). If you try to run it in Israel before then, it will give you an error. "
