Battles in Italy is better than Battles in Normandy or Korsun pocket because of the added scenarios and mods that people have made for it. Don't know why Battles in Italy became so much more popular (probably because there's not that many Italian front games out there and it was the 3rd in the sequel so had to have more props and tweaks). At any rate you get more for your $$ getting Battles In Italy vs Korsun or Battles in Normandy.
As far as what KISS means it's KEEP IT SIMPLE STUPID made up to tell developers that most gamers don't want these complicated nightmares like TOAW or WITP with all the numbers and sub numbers and sub numbers of the numbers sub. I hate a game that has 3 popup windows you need to go thru to see what kind of power you have or much of this or that you have or need. Just give me a damn number and let me attack with it. One number is all you need you don't need 10 bazillion numbers to have a combat. This game looks like you fill a core counter with relative units of different types and the game does the rest. We don't have to actually go inside each unit every turn to figure out it's strength do we VIC? I mean the numbers we see on the outside represent the units strength right? We don't really need to know if it's 1st division or 2000th division or what it's movement factor is vs this or that do we VIC?. The game tells us how far it can move when we click on it isn't that right VIC?

Some sort of shade on the maps shows how far it can move? And when we go into a battle it shows the odds right VIC?

hehe At any rate if it's not much more complicated than Peoples Tactics then it will be fine. It doesn't look that much more complicated from reading the aar's and listening to Vic and Twiller go on about it. Then again I might be having expectations of something SIMPLE STUPID and VIC has made a nightmare of a game. lol We'll just have to wait and see from the DEMO VIC is going to make RIGHT VIC? hehe
WE/I WANT 1:1 or something even 1:2 death animations in the KOIOS PANZER COMMAND SERIES don't forget Erik!

and Floating Paratroopers We grew up with Minor, Marginal and Decisive victories why rock the boat with Marginal, Decisive and Legendary?
