While I really like the world of T2K4E, I have always envisioned a game that is modern based. A game that can use the world as it's playground, and one that allows multiple choice characters per mission or adventure. T2K4E has a pretty good handle on the combat aspect and such a game would not change it much, if any. However, I know it would require more developed background material and some changes to character creation to include characters that are not purely military (which it already does to an extent). An increase of specialized skills tied to maybe one or more abilities, and other things like modern equipment, weapons, etc.
Some of the things I plan are Contacts, Assets, Professions (for those that are part time), Lifestyles, Renown, Reputation, Foot and Car Chase Rules, Lists of Terrorists, Anti-Terrorists, Criminal (Cartels), PMC's, Intelligence Agencies and other Organizations. A mission creator and other aids to speed up a GM's job, etc.
My question is do you think this is viable using T2K4E as a base and what would you include or remove if you were thinking about something like this.
