and what about "simply"
adding, from the beginning of the game and hence showing each year, all the tournaments that are possible each week throughout the whole 1990-201? period? For instance, week 1, Atp Tour, Adelaide 1990-2008; Brisbane 2009-201?; Wellington 1990-1992; Doha 1993-201?; maybe Chennai ...
It means that you could still chose to play Brisbane in 1991, but also Adelaide instead; you could play the AO on plexicushion back in 1995 - or on green synthetic
Would it mean too many tournaments for the game to handle?
And I'm aware the points system has to remain the same throughout the whole game.
And of course, I don't include the ITF tournaments in this tentacular concept.
Sorry if this was already discussed.
