Six Nations 2022: Marcus Smith, Rob Baloucoune, Rory Darge and Taine Basham
Hostile away crowds, loud and loyal home support and old rivalries everywhere you look.
The Six Nations returns on Saturday and, for some, it will be their first chance to shine in the iconic tournament.
They may have already made their debuts in the slightly gentler summer Tests or more challenging autumn internationals but the Six Nations will be another step up.
Here, BBC Sport highlights six tournament newcomers to look out for.
England fans hoping Marcus Smith would get the chance to spice up their side's attack finally got their wish in the autumn and now it is time to see how the 22-year-old stands up to the intensity of the Six Nations.
Smith is known for his creativity at Harlequins, but he proved he can get the serious stuff done too with a nerveless penalty to seal victory against world champions South Africa in November.
Facing Scotland at Murrayfield on Saturday presents another challenge for Smith and Quins team-mate Danny Care believes he is made for it.
«I do think Marcus will thrive in the environment,» Care said on Rugby Union Daily. «He will absolutely love being the main guy for England going up there.»
Full-back Melvyn Jaminet took full advantage of Brice Dulin's absence in the autumn to make his mark on the France team.
The 22-year-old kicked 20 points as Les Bleus claimed their first victory against New Zealand since 2009.
During the summer, Jaminet also kicked the winning penalty in France's first away win in Australia since 1990.
Should he get the chance to add to his six caps with the impressive Dulin back in the mix, Jaminet will be hoping to make more history in a tournament France have not won since 2010.
