I'm continuing to keep my eye on Tennis World Tour but I feel it will be a really long and "slow" process before the game sees the improvement it badly needs (if ever), as things stand I can't get away from how much of a budget game it looks in pretty much every area, I worry how long the developer will continue to improve the game and their customer communication is awful, also the price of TWT is totally ridiculous considering it's so unfinished.
Personally at the moment I just felt AO International Tennis was a no brainer to buy over TWT, first and most important although I have things I want to see improved in AOIT I feel more confident of Big Ant delivering the continued support the game deserves, I've been impressed with their patch support up till now and hope it continues for a good while yet.
For me AOIT just feels like a more polished product and has many little details in the game that to me make it a more authentic tennis experience than TWT, I hope over the coming months Big Ant can really push on and get even further ahead, I'd love for them to add a few more players to the roster as it lacks in this area (not including created players here) with only twenty currently licensed, I fully appreciate that's not always easy to do but if they could add a few more big name players it would only help the game and also be a real statement of intent going forward.
