Sorry, your wrong about the Outlaw Series? How do I know this? Because, I played them all, including Outlaw Tennis, which was released in the end.
If I remember rightly, it was made partly by MTV Games (which was actually closed and still owned by MTV..) and published by Take-Two, EA's biggest rival! The fact that it had courses that weren't real and characters that were fake (in more than one sense) meant it was never a rival of Tiger Woods. Sure, EA did nick a couple of features, but that was it.
Truth be told, they stopped making them due to bad sales by the looks of it. It was a very 'niche' title with an 18 rating.
How does it relate to WGT? I wouldn't worry. Sure, EA want to be better than WGT, but the fact that EA have had to up their game says something. In a recent interview on 'Inside XBox', someone working at EA said that Augusta was going to be 'the best looking course ever seen, better even than our nearest rivals'. Now, he didn't name the 'nearest rival', but who do you think it was?
I'll give you three guesses...
