Kingpin — Life of Crime

This is a really surprising game for me. I did not own Kingpin when it first came out in 1999 but I remembered the controversy surrounding it. A friend of mine recommended I check it out last year and I am really glad I did. I discovered an unusual but very interesting singleplayer campaign whose lacklustre story is made up for with some really cool game mechanics and fantastic environmental design (Viktor Antonov of HL2 and Dishonored fame was the art director). With MH's patch (very easy to install) you not only benefit from a bunch of fixes and modernizations but you'll also be able to join multiplayer games. Kingpin games are played every Thursday and Sunday. I can confirm that the KP community is a great bunch. In addition to deathmatch and the amazing Bagman mode, the community had added tons of maps, new game modes, and they even host seasonal events. Highly recommend you give Kingpin a look if you want a unique Quake engine game experience.
