The above list contains only
standalone games, currently in print, that have a modern setting by default. Games marked with an asterisk are d20 System and/or OGL games. Gmaes markes with two asterisks are available for free download.
Note that there are also
dozens of non-setting specific systems such as The Window, GURPS, Rolemaster, HERO, EABA, Theatrix, Formless, BESM, Savage Worlds, and so on that have no default setting and can easily be used to run games in
any time period.
As to what I like? All of the above, with the possible exception of HERO, which demands a
lot of work in return for very little payoff where non-fantastic settings are concerned.
