I have a Wii that I rarely play unless my friends come over. (It's hacked BTW.) Is it worth selling for a 3DS? Any suggestions? Thanks.
Well I own a 3DS (but not a Wii), and this is how I see it...
1) You never play it.
2) Nintendo has no more real first party games coming out for the Wii (except for the new Mario Party that just came out).
3) On the other hand, 3DS has PLENTY of good quality games, both available and upcoming. And being a young system, it probably has at least another 5 years of life in it (considering the life span of previous Nintendo handhelds)
3) Wii U is coming out at the end of this year latest.
If I were in your position, this is what I would do: I would sell the Wii, but keep whatever games and accessories I still like. Then buy myself a 3DS, and then buy a Wii U when it comes out. The original Wii is only going to continue to drop in sales value, even more so once the Wii U comes out, so if you're planning to get a Wii U, then selling Wii earlier is better.
But this is all just my opinion. Do whatever you think will make you happiest.
