A, very kind, remark about one of my objectives on the Lead Adventure Forum inspired me to put together a look at my growing collection of gaming markers and objectives, you'll notice that many are on 50mm bases to be used for Secrets of the Third Reich, but they still work fine for Super System.
There are some great pieces hiding in the various Heroclix ranges, especially the Organised Play Rewards, which can go for quite cheap once they've fallen out of the meta. Above you can see the Clix M'Kaann Crystal and Cosmic Cube as well as Young Hellboy (great for Golden Age games) and a fun little marker that came with The Question.
A couple that see service in SOTR, a stack of containers and an injured soldier still work for Golden Age Supers and pulp games. A packet of 1/35 Jerry Cans and some bases can give you all the objectives you'll ever need.
I was given a couple of these GW Tyranid "growths" a while back in a box of spares and thought I just had to do something with them. Some Liquid Greenstuff and a few spare parts later and I came up with these two grotesque beauties. I tried to paint them a bit like the "Creep" from StarCraft to make them more generic.
I love scratch-building. Its a challenge and it clears out my bits box (bits garage, whatever). Above you can see "The Football" and Mjolnir, my two favorites of all my objectives. The football is a 1/35 briefcase, zombie hand and a piece of chain from something. Mjolnir is a small rectangle of carved foam and the handle from a GW Beastman weapon. Both simple, both look great.
Hope you gleaned a few ideas to add that little more to your games.
