Autodueling and such!

[2097]

Not sure whether this should go in the Car Wars forum or the GURPS one.

OK here's what I have:

• A white box of "Car Wars" from 2014, 2015, or 2016. That's 4th ed, right?
• GURPS Autoduel for the original GURPS
• GURPS Autoduel Car Warriors also for the original
• GURPS Autoduel Second Edition for GURPS 3e
• GURPS Action 6 Tricked Out Rides for GURPS 4e

The older GURPS Autoduel book says:

When there are a number of vehicles moving at greatly different speeds, the GURPS movement system becomes less realistic. For those familiar and comfortable with Car Wars rules, feel free to use the movement system from that game.

The second GURPS Autoduel says:

Some players may find themselves saying, "That's not how they do it in Car Wars!"
Of course not. This is GURPS.
However, when the PCs jump behind the wheel and head off into battle, there's no reason that the GM can't pull out the old turning key and switch to the Car Wars movement and combat rules. This works particularly well if you like cinematic battles with cars spinning 90° about at 60 mph in a fifth of a second.

It seems to be a very different system. It also says that there are "vehicle construction rules compatible with GURPS Vehicles" but I can't find 'em. Ah, dammit! Another page says

For the dedicated GURPS players who want to jump into the world of Autoduel, the mechanics of vehicle construction, weapon design, movement and combat are laid out in GURPS Vehicles, Second Edition. You will need that book to play GURPS Autoduel.

So why did it say that this book does have those systems

So the GURPS Autoduel first version still uses a turning key, saying that the grid (and it provides hex and square options) are only for placing houses. It seems to hew much closer to Car Wars

Anyway that's what I have currently. Looking to run an RPG campaign primarily, with a GM and adventures where my friends can go on car fights or just do whatever in a sandboxy world. But it seems like what I have here is four slightly different games.

I have the Basic sets for 3e and 4e so if I go the 1e route, I'm gonna have to get that basic set. Or if I go the 3e route I'd need Vehicles it seems like (contrary to what the back of that book says). And for 4e, I have Action 6 and 7 (and remember reading the first two way back), probably I'd have to go get some of the other ones.

Not sure what some of the pros and cons are of all these options
