Trivia: Rainbow Six
- The Other Darrin:
- John Clark was played by Willem Dafoe in Clear and Present Danger, but the first game had him voiced by Douglas Rye instead.
- Between the two Vegas games, every voice actor except Jung Park's was replaced. Particularly notable in that a lot of the characters in Vegas 1 had distinctive accents that, except for Michael Walters, the replacement actors did not bother to replicate.
- Name's the Same: One of the major team members is (Eddie) Price, who is characterized as The Lancer in the novel. Like another, later well-known Price, he's an ex-SAS operative, now transferred to a multinational anti-terrorist team, with a magnificent mustache (the only member of his team to have one) and almost the exact same voice and accent.
- No Export for You: The South Korean-made game Take-Down - Missions in Korea. It was suppose to get a worldwide release, but it never happened.
- Recycled Script: The plot of the Vegas games is very similar to that of the Black Thorn Expansion Pack for Rogue Spear, though considering the obscurity of the expansion, it might have been accidental. The plot of Black Thorn involves an ex-SAS operator, who failed to get into RAINBOW (thanks to Cold-Blooded Torture, leading to mental problems), masterminding terrorists attacks worldwide to prove how good (and petty) he is.
- What Could Have Been: The first game in the franchise began life as a tactical shooter based on the FBI Hostage Rescue Team. It was changed to an adaptation of Tom Clancy's novel to give it more appeal to international audiences. Amusingly, the devs later got to basically make the game they originally envisioned; the Licensed Game to The Sum of All Fears puts you in the shoes of the HRT and plays very similarly to Rainbow Six.
