Why should I do that?

Yes, yes I do.....

 so u can be a true nintendo fanboy and also get pikmin new play control!

 It always amazes me that people will ask for someone to point out how they are trolling? Do you really think no one can see it? I shall explain it to you in great detail then. I will give you some props for getting it past at least one mod.

 You created a thread talking about how you got a Wii. You then go one to explain you got screwed over for getting a ton of games and a fully working Wii with two controllers and a balance board. You then ask how much you can get for various games which can be determined with about 10 minutes, and access to eBay. When people recommend games you shoot them down saying you have no interest in playing any Wii game, but still traded in your speakers rather than waiting for a better deal to come along.

 So what we have here is you creating a thread in the Nintendo section asking for advice most people wouldn't be able to give. You could have gotten more useful information much faster by simply going to Amazon, and eBay to check the prices these games sell for used. The only other reason to create a thread like this is to get a reaction out of people. Posting extremely negative opinions simply to get a reaction out of people is commonly refered to as trolling.

 So in light of all of this I have a question for you. How is this thread not trolling? You had to know the reaction you would get while creating the thread. It is extremely obvious you wouldn't get a ton of useful information from Nintendo fans as they don't liquidate all the games they have for a console they enjoy. What were you hoping to get here that would be better than a quick internet search of websites designed to help you re-sell stuff you dislike.

Ok, this amazes me because I thought there was nothing you could consider trolling. But I guess I have to reply you.

Fully working wii with balance board is not worth as much as I wanted for those speakers so it is a quite bad deal. But if you know what kind of nagging you can get from your GF about 2 big speakers taking a lot of room you might understand that I just had to get rid of them as soon as possible. That was the best offer from people near me (guess do I want to ship those speakers) so I settled for it. I guess it is pretty normal to sell your unwanted items, right?

Also we don't use ebay or amazon here, there is really only one web auction site and it did not have enough of those items for sale to get a good clue about the prices.

Even twesterm is too lazy to look up how much he'll get for a game, or even decide what game to play that he already owns. So does he troll the Wii too? (maybe this is a bad example, as people claim he trolls everything )

I don't care if he traded his car for a Wii with the intent of selling it. Maybe he is just stupid, but he asked a legitimate question and you and everyone else just derail this thread. He never asked for games to buy, all he wanted was how much he'd get. The thread would be 1/2 the size if all the "OMG he is trolling" didn't take place and people just answered the question.

This is the same exact thing that happened to Starcraft when he legitimately made a thread that got derailed so bad that I locked it and he had a lengthy conversation with me over it. Sometimes people change, sometimes they don't, but if you don't give them a chance, then you'll just continue to argue and not get along.

I have had my small system in my room for 6-7 years, and there is nothing wrong with the speakers that came with it... the whole lot was just under £100.
Ok so I have a small room, I think the wattage for the combined 2 speakers (zomg only 2!) is probably less than 30.

In the living room we have had a bigger system for about 10 years, speakers still fine, I believe it was about £200 when we got it, the only thing that went wrong is my dad nicked one of the speaker wires when putting in a new carpet, so it started cutting out, but we shortened the wire and it is fine again.
I believe they are about 60Watts each.... and it sounds good.

And you can't say I have bad ears, I went to see Star Trek at the cinema a couple of days ago, and I could hear they turned the cinema speakers up too loud as there was a buzz in the explosion sequences.

 I am not saying the speakers were not worth more. I have shit that would be worth way way more than what you describe if traded in, and would be a bad deal if I did it. However, putting the line about getting a bad deal while referencing the Wii will only serve to piss people off. Its a nice way to call the machine bad without anyone being able to point out you called it a bad system. It would be a great bit of stealth trolling had you done the thread in a better way.

 A quick search on amazon.co.uk (where your profile says you are from) shows a nice selection of games used on the Wii and an accompanying price. I find it extremely hard to believe you expected to get better information out of a bunch of Wii fans on a website with a plurality of people living inside the US, and only a notable minority living in the UK itself.

I am from Finland, I don't know why my profile says UK. Propably because I haven't entered that info. :P

This explains so, so much. Mostly, your username.
