Alun Wyn Jones says international rugby is continuing the trend for more open play which started on the final day of the 2015 Six Nations.
Ireland won last year's title on points difference after a dramatic finale.
"I think it's probably a development off the back of the World Cup. It's not a question of defending leads, points win championships," said Jones.
"That seed was sown on the last day of the 2015 Six Nations where everyone was playing for points difference."
Jones will win his 96th cap for Wales against Scotland in Cardiff.
"With meritocracy in the Pro12 (playing for European qualification) and coming off the back of the World Cup, teams are playing for bonus points and tries, it's a positive, and it's started the same way in the Six Nations," said Jones, who has scored eight international tries.
But the Ospreys lock admits Wales need to improve on taking chances after the opening draw against Ireland saw both sides restricted to one touchdown apiece, despite plenty of attempts from either side to play a wide game.
"I think we had enough opportunities I felt we should have taken. We probably did enough outside of that (half-back) axis to get a few more points on the board," he told BBC Wales Sport.
"We've got to let the ball go and take those opportunities. I said that in an interview we had last week, it's very similar to what we experienced in the World Cup - we are trying to correct that but it's not going to happen overnight. I think you can see a definite shift in the attempt to play that way."

Jones, 30, who signed a new national dual contract in January, believes the game against Scotland will also benefit from the coaches' agreement to play under a closed roof.
"The boys out wide will be happy because there'll be no rain, but it's good for the occasion, it's a great facility that we have so why not use it."
Jones is appearing against Scotland for the eighth time with six wins so far, although he is the only survivor in the starting 15 from Wales's last defeat against the Scots in 2007.
