(First, I should point out that I have not yet tried the game with the 1.03 patch. Second, I should say that I don't mean this to be an RT vs. WEGO diatribe.)
With the various AI and pathfinding issues that existed in the 1.01 release of the game, I started playing RT because, to be honest, that seemed the only way to play the game without extreme frustration. I'd initially felt a reluctance to do it and I missed the playback feature in RT, but overall I liked playing it.
That said, unless you don't use the pause button, RT makes things too easy on the player. IMO, the joy of playing WEGO is that you have to set the situation up with unit positioning, moves, and timing to your best advantage and then relinquish control, sit back and watch to see whether you did it right. Basically, after you had issued the general orders, you left it to the TacAI to carry them out - I know it wasn't totally realistic but it seemed more realistic to me.
In RT, you don't have to do that - you get to pause the game and correct your flawed orders on the fly. I still enjoy playing the game that way but, to me at least, it feels in some way that I'm "cheating." The obvious answer is for me not to use pause but I'm not sure that's a realistic option for me either.
So to conclude, it's not that I don't like RT, it's just that I'd prefer not to use it but currently feel I have to. Here's hoping that 1.03 will let me back into WEGO.
p.s. I also read some posts that suggested a shorter interval for WEGO (like 20 or 30 seconds). I think that was a great idea.
