Being something of an old grognard... I don't have as many games as I used to, and I have even less time to fiddle with them, alas, but I have a certain fascination for the rules systems if nothing else. In terms of ACW naval games:
- Ironclads and Ironclads Expansion Set (both Excalibre and Yaquinto editions)
- Shot and Shell (3W), a sort of Ironclads-related game-- not quite an expansion, but fairly compatible
- Ironclads and Aether Flyers (from the Space: 1889 roleplaying game)
- Blockade Runner
- Iron & Oak
- Rebel Raiders on the High Seas
- Smoke on the Water rules
- Iron & Steam rules
- "Victory on the Rivers," a Victory at Sea rules variant for ACW
- and from a slightly older era, the good old classic Wooden Ships & Iron Men
and I *think* I have
Hammerin' Iron around here somewhere, though I can't put a finger on it at the moment.
On the computer, I have
Ironclads: American Civil War, which I really don't care much for, and
Ironclads: High Seas, which is a little better but still not all that engrossing to me.
One of these days when I have loads of time again...
