- Are you able to move around people with any remaining % activity for movement in the middle of a melee situation (after the deliberate phase)?
In other words, if, at the end of round 1 in a melee between player1 and orc1, player1 has activity left so can he use that to flank Orc1 so that next round, he'll get higher OB due to position?
If he could, what's to stop Orc1 from doing it too?
And if they both did it, would they simply dance about or potentially be 2 hexes apart?
Short Answer is no. Turning in place takes no action, IIRC, so all the orc has to do is to change facing accordingly.
- Also, is player1 able to break off melee with orc1 to attack orc2 that happens to be in the process of killing player2? Would orc1 get in a free strike on player1 before he disengaged or would he only get to do that if his initiative was after player1's move?
Yes, player 1 can break off to go save player 2. No, the orc will not get a free attack (there are not such in RM), but the orc might possibly get to make an attack with positional bonuses depending upon the situation, and how much movement is required for him to stay with the player.
Even though the player breaks off from the orc, the orc is unlikely to stop attacking the character...
- Also, are there any penalties to moving past other combatants engaged in a melee? (besides a difficulty level for a maneuver roll) - I'm thinking free strikes on that person, for instance, if player3 wanted to pass by a melee situation with Player1 and orc1.
RM does not have free strikes (i.e. Attacks of Opportunity) like you can find in other games. Then danger comes from the other combatants having percentage available to make attacks.
- If player4 had a bow and was attacking orc3 (poor orcs, I know), could he keep backing away out of orc3's movement range while firing at him?
I think that pastaav answered this one quite well.
- What's to stop everyone declaring that they'll move around an opponent they're already engaged in melee with to gain the flanking bonuses in their snap phase and then attack in their normal or deliberate phase?
As explained above, a foe can always change facing so that you do not get those bonuses - that is essentially a free action, plus one that is usually considered a given -- no foe is going to allow you to get behind them if they can help it.
And don't forget - even though there are 3 phases, you still only have 100% activity for the round. Thus, taking 20% move to get a +15 flanking bonus is kinda silly since the attack itself would be at -20 because of the move in the first place....
In order to get into a position where you can flank a foe (after facing him), you would have to perform a sudden, unexpected move on him (i.e. suddenly doing an acrobatic maneuver to get flank AND rear positional bonuses). A simple move won't work because the foe will always just turn to continue facing you.
Combat includes movement, back and forth or what have you of both combatants. For the sake of simplification, it is considered to cancel each other out when compared to that of the foe.
