My first simultaneous movement game was "Starfleet Battles". I purchased the pocket games back in 1980. Unfortunately, they turned a pocked game into wargaming tax code.

I love the term Panzerbushing, there were definitely some weird things you could game in Panzer Blitz, that they kind of fixed in Panzer Leader. I don't so much mind IGOUGO, but in most games fire at least should be simultaneous (this rewards good tactics even while you may be penalized by bad dice).

I am a big fan of Bolt Action, since you move or move and fire, or ambush during an activation.
