First "wargame" I ever played was Tactics II. It was about as "realistic" as chess is frankly.
But the important thing to contemplate when determining "realistic" is not how much game is present, but rather how realistic is the game that is present.
ASL rules the heap from brutally realistic. Steel Panthers through a Mega Campaign is brutally realistic. Panzer Leader is a greater deal of simplicity in design, but I think it simulates warfare realistically enough.
Close Combat is realistic mainly because the game kept the unit density to a level where the realism was preservable.
Sudden Strike 2 dropped the ball entirely in my opinion. Just providing "accurate" looking icons does not a realistic game make.
The action has no credibility, and therefore you can write a several page long graphics included fully detailed "review" of the game, and frankly I don't care squat what your "professional" qualifications are, the game is still junk.
I recently tried Blitzkrieg's demo. And if you check out my thoughts on it at Wargamer, it's clear, my view is not inline with the "preferred" view. The only reason I let the matter drop, is because I said my piece. But I have to also perform my function as a moderator, and therefore I can't spend all day every day beating up on some games.
3d is to some the way of the future. If I had a dime for every thing that was "the way of the future" I could buy my next wargame free.
Real time is to this gamer rarely about anything tangibly or usefully free.
Match an organic computer (a human) against an electronic data processor (a computer) and arguments about "real time" become the rants of idiots.
Thus far the only thing I have seen using 3d in anything like a worthwhile manner is Combat Mission. And that is entirely because it is a WEGO system. It matters not how much you fiddle with your turn, it won't resolve till you formally hit end of turn and let it process your moves against the computer's. The organic computer suffers no disadvantage to the electronic computer.
I have seen the real time approach work. Close Combat works. I also think Tac Ops and Airborne Assault have a good handle on real time. But then the game isn't mired in 3d.
3d real time is possible though, anything is possible, the second the designer is capable. And that is just it, there are no shortages of completely incapable designers out there obviously.
And we have reviewers stroking these clods only making things worse.
Saying Blitzkrieg is worth shiit is like offering candie bars to a fat person, not helping any.
I am not sure it is any major "wave of the future" per se, but programs like VASL might very well be a major determinant in what constitutes what we label a wargamer in 5 years.
It might come to pass, that we call people that play simulation accuracy first and visually amusing second types, wargamers, and people that are only interested in visually amusing, and not willing to accept dedication to simulation accuracy as nothing more than just another "gamer".
Right now I don't think the label "gamer" and not "wargamer" is a slag. I don't expect everyone to want to play my wargames. I don't "need" everyone to play my wargames. I don't care if my hobby starts remains and continues to be a niche hobby. I don't need mass market type sales.
I also don't have sympathy for retailers/producers/designers that leave themselves with no other way to make an income. Stores know they need a cash cow to stay afloat, and wargame producers might as well wake up and smell the same reality.
If my favourite maker of wargames suddenly starts to produce games that have zero in common with traditional wargames, I won't be screaming "betrayal". It will just be a sign the company has finally hit the big time. As long as they remain true to the actual wargames I like, when actually making the wargames I like, there won't be any trouble.
I will of course only be buying wargames of the style I like, from people that make wargames the way I like them. Makes sense eh.
