I got a Challenger and a Brit infantry squad today (my LGS screwed up my order, so I'm still waiting on my MEA troops and another squad of brits), and I'm so impressd with the paint jobs. the faces are th eonly problem on the infantry and the eyes aren't so bad - they only look crappy from certain angles, and the camo is really well applied. The only bent parts were the bipods on the LMGs. If I do any touvhing up at all, it'll be light washes to dirty them up, and maybe drybrishing a couple of the more orangy bases with bleached bone.
The challenger also looks great, but the mini has no weight to it, which feels very odd to me - I've not played a 28-30mm skirmish game with tanks in in a long time so I'm not used to how much they should weigh. But as it is, it feels a bit too much like a toy tank - especially as the bottom panel was loose and I could see it was totally hollow on the inside. Killed the illusion a little.
I'm very pleased overall, the paint jobs aren't perfect, but they're as good as I can do, so who cares?
As for the rules, I've not played any BF:evo yet, but I have been playing a different game with the same ruleset, and I totally love them. And the advanced rules will only make it better
