I think a samurai game would make good use of anolog sticks.
Hear me out: The left for movement of your character and the right for moving your sword.
So to slash (for example ) you move the right analog from up to down to do an over head strike. Left to right to do slash across the belly from left to right. from down left to upper right for a rising slash in those directions. you get the idea.
I guess you could do the same with a mouse too. Hold down the mouse button and move the mouse in directions for your slashes, with number pad for movement ( to include diagonals ). Hold down the other button for block moves ( with the same idea as slashes ). Same with the controller option, hold down a button and move the Slash stick for blocks. Thrusts with spears are handled the same way, mostly from down to up commands for thrusts ( back and forth )
You could pick up armour pieces on the way which you can repaint for customisation. But armour slows your movement and slash speeds down a bit.
Or you could go no armour to keep light and fast.
I read some where ( citation needed ) that the first ninja were samurai any way. So you could also go the ninja route. Holding down a button while you move for the slow / stealthy movement. LOS and shading adding to your stealth.
No leveling, no power ups. Just the skill of the player and the speed with which he can enter his commands. ( much like real samurai then ). Just simple slash commands. But repeated use of items increases your ability with them. So slashing for 8 hours a day for a month with the same sword makes your stikes with that weapon faster and stronger ( so i guess leveling of a sort, but a more realistic practice over time )
Realistic weight distributions, so cant carry an arsenal of weaponry. But you could get yourself a Diaymo (sp?) to use his place as a strong hold so you can change weapons if you want. Or perhaps just stash it in a cave somewhere.
Im not sure how to handle the death mechanic though. I guess as there is no leveling it could be a reincarnation thing, where you come back as some one else. Obviously being the player you know where your guy has stashed what ever loot he had, kinda like a spiritual instinct in the reincarnation regards.
Not every strike is deadly, but nearly always leaves you bleeding, so medical attention must be sort / self first aid applied. Bandages and Balms would probably the most readily available. ( again repeated use increases the likelyhood these will actually work ). So that gives you items to collect outside of weapons and armour.
With your primary weapon put away using the Shoulder buttons in conjunction with the slash commands allows you to strike with unarmed attacks ( foot attacks allowed with weapon drawn, hand attacks when a one handed weapon is drawn ), the slash stick defining the target area / angle of the attack.
Food gathering gives you something to do aside from killing oher people.
I think a Rest ( stamina bar ) and hungry / thirsty bar then.
Im thinking of profession work as well. But i see using the slash stick to strike a piece of metal to shape it into a piece of armour / sword rather tedious. But for those who want to spend 10 hours striking a piece of metal, feel free...
Doing these tedious task makes your (stamina) bar decress slower if you do them long enough. Like endurance training.. Help the locals build a fortress wall, lugging one stone to the wall at a time. Holding the run button down while moving around for extended periods. Swimming in the rivers.
Bowmanship: I guess push a button to enter "sniper" mode with a bow / xbow / throwing weapon equipped. Things like the wind effect your shot, but effectively the item goes "straight". Again repeated use helps the "straightness" of your shot / throw. So obviously the closer you are the more likely you are to hit the target, but also more likely to be seen by your opponent.. can you get the shot off in time, accurately ?
All the "training" your guy does is a sliding scale. So if you dont use a skill for a length of time the slider goes down, and you loose a bit of skill with the action.
I guess though there is no upper limit, bu tthen you can only ever be so good at something in Real Life. But i dont want people to see the slider bar and try to keep everything maxxed out to be the most effective.
A lot of it has do with the player controlling the character though, and they might be having a slow day and get slashed by a newby sort of thing.
Which again kind of reflects your character having a slow day. probably should have stayed at home today.
So yeah thats all i can think of for now.
So would you play it ?
