The ATP recently published its calendar for 2015. The biggest change from previous years will be an extended, three-week grass court swing between the French Open and Wimbledon. Halle and London Queen's Club will be upgraded to ATP 500 events to give the grass courts more weight in terms of points and prize money. Stuttgart, s'-Hertogenbosch and a new 48-seat tournament in Nottingham will comprise the rest of the grass court season.
I like these upcoming changes a lot, so I made a mod for Tennis Elbow so we can already play the 2015 calendar.
The mod features the complete, accurate 2015 calendar for the men's main tour. The Challenger Tour calendar for 2015 has not been announced yet, so I am using the Challenger tournaments from my 2009 calendar, which are a good fit for the 2015 season in terms of scheduling.
I dislike seeing top players like Federer, Nadal, Djokovic etc. playing an unrealistically large number of ATP 250 tournaments, so I have changed this. The top four players will only enter the well-paying, season-opening ATP 250 tournament in Doha and skip all others. Another improvement over the "vanilla" game is that matches at the US Open now feature a 5th set tie break.
Unpack the zipped files to the game's /data folder, and have fun!
