Solo Sci-Fi

I can't speak to the rules and there are some great options already mentioned.

What do you have on hand as far as scenery?  I love toybashing and custom terrain but if you're trying to put together a multi-scope campaign and don't already have a stock of scenery, there are some excellent affordable card options.

The three Infinity terrain packs are ridiculously affordable...

... and for 6 or 10mm the Dropzone commander Terrain pack is a whole city in a box.  Both look quite good and will let you concentrate on getting your minis prepped and played with.

Best of luck with the campaign.

I've been thinking about terrain today actually!

For space combat I've got a hand-painted game mat that will work. For urban, I'm waiting on the Battle Systems kickstarter to get delivered (extremely excited for that). Beyond that I don't have a ton on hand. Great tips on the Infinity and DZC stuff, will check it out.

I'm waiting on the Battle Systems stuff as well  I keep on almost buying their SF set, but haven't quite done it yet.

Some of the Dropzone Commander buildings are available as free downloads - http://www.hawkwargames.com/pages/downloads

I think I rescaled them to 6mm when I printed them out, although it doesn't matter so much with skyscrapers.

For solo sci-first I've recently quite enjoyed the Rogue Planet ruleset, very simple and good fun to boot. Also the vagueness and guesstimations appeal to my sense of the absurd.

For big battles i plan to use Dragon Rampant but with a few alterations i.e. Space marines as elite heavy foot, I'll also go with reasonable guesses for ranged weapons as in rogue planet , I find DR to be pretty streamlined (and since I'm only competing against myself I don't need to worry about measuring).

I used to make reaction tables back in the day, but now I just work on the basis of what might the opposition do, and what would be cinematic and spectacular if it works out! I suppose the dice rolls add the random and unexpected elements.
