Greatest tennis game I've played although there was also one on Super Nintendo that ruled as well. It was like the tennis version of Super International Cricket, since it had made up players and all. I so gotta pick that up on Ebay or something.
Anyway Smash Court Tennis Pro Tournament is absolutely awesome. I got it for my brother immediately when it came out during Wimbledon 2004. It has great gameplay and some awesome characters. Their serves and shots are almost identical its very well made. Virtua Tennis is a classic arcade tennis game, but its no Smash Court Tennis in terms of realism. I always go Safin and own the computer, although my bro still beats me. I once took him to 5 sets but I choked.
What's really odd is, despite the game clearly being aimed to be marketed during Wimbledon 2004, the game doesn't have Federer in it. I mean that's just a disgrace. Still rules though.
