Hello,
Do you know Song of Blades and Heroes? It’s a skirmish game easy to learn and fast and fun to play. Best thing is that you can design your own warriors (no “army books”) and there are nice fan-made Middle-earth based lists available for free. It’s the game I play now and I quite enjoy it.
Here you are a review: http://wargameguru.weebly.com/in-focus-review—song-of-blades-and-heroes.html
You can buy it online in PDF format for 5 € and is available in English, Italian, German, Spanish and French here.
And here you are the lists (they’re in Spanish but I can provide a Spanish to English skill list if needed).
