15mm scale Infinity!
OK... why? Because I've been looking for a decent skirmish game for ages, and I like the way Infinity plays - and I could get much more mileage from, for example, Ground Zero's 15mm StarGrunt SF range as far as troop minis go. Plus there's little need to convert for the right standard/support/heavy weapon types as they've a pretty comprehensive range, whereas the Infinity minis - at least when I first got the beta rules - were pretty limited.
As 40k players, my group have a lot of Gothic ruins terrain to play around in at 28mm scale, but I really don't feel that it fits with the Infinity feel... Being utterly awestruck and inspired by Matakishi's Infinity city table I really wanted to do the game justice - and experiment with modular terrain after seeing some great Necromunda ideas - and making new 15mm terrain would, I thought, be easier than making new 28mm. That was, after all, one of the things that put me off playing Warmachine...
I don't really get that much time for the hobby side of things, but it's still a dream. But first I need to get my ACEF fleet painted up for Starmada!
