Here are some more suggestions that I've been thinking about!
1. A watchtower - this would be a set that is a single, round tower with multiple levels with, say, sleeping quarters, a kitchen, weapons and armour storage, and such; of course, the top would serve as the lookout area where warriors would watch for enemies. This set would be extremely versatile, since it could be used for basically anything that a tower would be used for, including Fairy Tale uses. It could even come with multiple hanging banners for different heraldries, or these could be offered for purchase separately, within the Tournament Knight collecting sets that I mentioned earlier.
2. A wooden staff - another staff like (or a re-issue of) the one that looks like an actual branch in the older druid/wizard sets.
3. Vambraces or gauntlets - for the thick wristed figures; I dislike these thick wrists very much, but if they have to stay around, we need some sort of vambraces or gauntlets that fit them. The leather ones that have been out are okay, but they really aren't as good as the old ones for the normal wrists.
4. Monsters - it might be cool to have some monsters to fight, maybe with knights matched against them; these could be creatures based on those from real Medieval or earlier legends like Beowulf, the Nibelungenlied, the Mabinogion, or they could be completely original or well-known such as dragons, serpents, or the like. I know there have been sets like this, but it'd be great to have some new ones or ones that incorporate some of the older parts.
5. A European dragon - a dragon that is more similar to the older Playmobil dragons instead of the more cartoon-like ones of the Dragon Knights theme.
6. A Skeleton Horde - this could be like a new evil faction, made up of enchanted skeletons; they could have special armour made for them and get turnable wrists and heads that can equip helms and such.
Some cool ideas for some new Specials:
1. A Medieval Minstrel or Bard - with instruments, parchments, and Medieval attire.
2. A Medieval Maiden - could be stereotypical with birds or small animals, like the Dove Girl 4526; we just need more figures like this really.
3. Another Dragon Slayer - a new model of the Dragon Slayer figure, with detailed and magical looking armour and weapons, like the original.
4. A Smith - with apron, hammer, anvil, a few wares, and maybe a small bellows and some coals (if it's a Special Plus).
5. An Armoured Knight - just a knight in unpainted armour; I think it'd be cool to have a fully armoured knight that has no specific heraldry.
6. Falconer - a Medieval falconer with a few birds and maybe some feed.
7. Pigeon Keeper with cages - a keeper of some messaging pigeons, with little scrolls and a few in a cage.
I reckon that's all for now.
