To tell the truth , most game play type  and computer/ video game  questions just go right past . I’m just not interested in playing games . Never got the bug as a kid , too busy building models and reading . Never got into it as teen as rock concerts , girls , booze and cadets / militia plus model building was my focus . As a 20-30 something I was into model trains , and the last 5 or 6 years I got back into model kits although mostly 1/56 – 28mmm .   Nice to see well built and painted figures and kits but no interest in playing with them . Pus I can’t see the point of chain saw swords and power claw hands in a game with laser blasters  .   So that’s questions 1 , 2 and 4 sorted . # 5 – The game play part of a  boot camp would probably be wasted on me , but I’ld sure love to sit down and build tanks with John , or spend an afternoon picking through parts boxes to find bits to create unique figures . .

#3 Kit Bash and Converting are they the same thing ? I would say they varying degrees of the same process . You can give a plain jane basic cannon fodder Space Marine ,for example , an arm from another set , and you have a totally different figure than the other 4 same pose  guys from the box . Very easy to swap arms and  heads ,in some of the more human looking 40K figures , same as the Bolt Action plastics . Next level would be cutting figures off at the waist and then cutting the legs apart to create different walking / running poses . And then get a little more knife happy and start notching elbows and knees to create even more dynamic poses . Sci Fi , 40K vehicles are the same , substitute a turret from this kit onto that kit , now its something different and new . Historical vehicles need a little thought as you want to have a basis in reality . So you could remove molded on tools or tow cables and add parts to give the model a more 3D look . Or you get out the plastic card ,green stuff,  resin and pewter  bits  and change the vehicle into something  that isn’t available from your favorite hobby company . Here’s a couple of examples of kit bashes and conversions . 1st is a British seated figure from the BA plastic Universal carrier converted to a German Panzer crew man by changing his uniform with thin plastic card , green stuff , plus a metal head

Next up , Russian Cavalry made by combining Perry Civil War Cavalry and BA Russian plastics

To get troops in the rear of my M3A1 half track , I just swapped legs around . The troops all have 1 leg up on the seats , the other on the floor so they can be facing / firing out of the vehicle . A little trial and error to get them to fit but worth the effort

Next is changing the Spider style mid/late T-34 wheel to a early war dish style . There were about 12 different T-34 wheel styles during the war , and the ones BA uses on the 76 model is wrong for the 1940 turret . So I just got a very small (1/8 inch ) chisel blade and removed the ribs .
