Driftr buddy... I don't know whether to say "welcome back" or "welcome to GTPlanet," so I won't comment on anything related to that.
As mentioned, online play was the bigtime feature. Does it mean that GT4 is nothing without it? If Tom Brady wasn't the starting quarterback for the New England Patriots, would the Patriots miss out on a chance to win another Super Bowl? If Michael Schumacher wasn't in the race, would it mean that another blowout wouldn't still happen? I've been on the premise that it's okay to be disappointed about no online play beyond LAN. You still have a solid racing game to be proud of, even if the AI is like bumper cars. So let's not be FULLY disgusted in GT4. You still have a great game of Gran Turismo racing. If America was disappointed that it didn't get the fully tricked-out Mitsu Lancer in 2001 or 2002, did we fret? Well, many of us did. But a couple of years later, we get the Evo VIII. And all the Lancer owners wanted to do one thing best: PWN the Imprezas. So while it's going to take time for online play, you can be a little more patient, yes? If us GT fans waited for two or three years for GT4, then the wait was for a good cause.
I'm expecting some negative comments, but if you ask me... if you like GT4 and you wanted online play, get GT4 first. Be sure to enjoy and savor the experience. Because when the online-beyond-LAN version comes out, you'll be able to appreciate the multiplayer experience, but not before understanding what the single-player experience is like. Sure, more money down the drain over the course of at least Dec 2004 and Dec 2005, but that's why you can sell the non-GT4 version to a game store or something. Like I said. One word. Improvise.
