*COUGH*
He is *how* old and he's beating you around?
God's sake I thought up till this post the older bro was 14, maybe 15. *18* is more than old enough to know not to hit someone, esp family members.
Alright, time to whip out some old fashioned sneaky tactics. There's a reason I read Machievelli before I left for college. This one might be a little long, but some of the principles will serve you well.
Analysis of the situation:
1) You have a brother, with violent and aggressive tendancies. He's in your face, in game and often out of game. Abusive to yourself, and probably not too nice to your friends either I'm willing to bet. I doubt they would miss him much from their games, yes?
2) Said brother will be leaving, eventually, but is likely to return during summer breaks etc. Aka, you will still have to deal with him eventually.
3) Your brother is also dependant on your parents, who - from how they split you up before when you were fighting, seem to at least care about your physical safety and getting along.
4) You can't really take him in a fight.
Here are some other 'givens' as well:
1) Your brother cannot kill you. The worst he can do is cause property damage or major bruising.
2) You will heal.
3) Your parents will notice anything big and painful.
4) Your friends are not required to play with him (as they have their own houses)
If you're willing to take the chance of a little bit of pain (for a better deal in the long run) and a small risk of property damage, here's one possible solution:
Given the above, the best solution is to stonewall him. Nothing kills a problem as quickly as a simple, calm, and emotionless response. Begin to 'handle' your brother instead of fighting with him. Move your game someplace else, if that is not possible, recruit your friends to back you in this. I don't think you'll have a problem convincing them to avoid him as well. Ask him to leave you alone (May need to explain to parents that you want time with your friends without him.) He can't run if they won't play. He can't play, if you don't run. And he can't *make* you run.
That's the critical part of it: He cannot *make* you run.
So what he'll probably do if this happens is throw a fit. (In younger people this would be called a temper tantrum.
) This is where your self control will be tested. He will try to make you angry, possibly hit you. If you don't get angry, and don't hit him then you won't be at any fault if your parents get involved. Feel free to remind him of this. (I personally like ignoring until they get frustrated and leave, or frustrated and make a critical mistake.)
The worst he can do at this point is hit you, and hit you hard enough that you can then go to your parents with it (again, do this with a completely calm and straight face and you come off as *completely* the mature one). He won't willingly risk his college, or his parents affects, just because his brother won't jump when he yells. He may not like you, but to be honest if he's kicking you around like this - I don't think his affection will be much missed.
So, to summarize:
*Handle* him, don't fight him.
Remain very calm at all times to convey the right attitude to those in authority.
Be willing to take a little bit of hurt, for a greater gain.
Being extra nice to him won't work. People are like dogs sometime at least for training their habits. Have you ever seen a family the fed a dog to make the dog shut up? It doesn't tend to work too well, because the dog sees this as a reward for barking.
Oh, and ask for your key back. Inform your parents you don't feel like he should have a key to your room if you don't have one to his.
You're actual experience, however, may be completely different.
