You can also unlock a Ghost Ship and Blue Mushroom house in each world as well (Blue in SNES version, white in NES).
Mhmm, the Ghost Ship is what I call the Coin Ship
And yeah, the Hidden Mushroom houses are annoying to unlock :/
Anyways, I hate my internet, it cuts off so randomly when playing multiplayer. Not enough to inturrupt online surfing or streaming, but just a large enough blip that, when in a middle (or beginning) of an online mission it'll cut out.
This is annoying because I was doing an online mission with 3 other people in MH4U facing a Dah'ran Morhan when it cut out about 3 minutes into the fight. On a High Rank mission. With a weapon I am just learning (Longsword).
Luckily I ended up beating the mission still, which I am proud of as i basically had to solo almost the whole thing, but the point remains.
Also, I am getting so good with the SnS. We fought a high rank Kushala Daora, and I ended up mounting him like 4 or 5 times in a row due to the rising mounting opportunity the SnS has (Mounting opportunity on the rise and descent in one go). We took him out in about 5 minutes, if even that (there where only three of us at the time).
So yeah, as I said in a post earlier, if you practice and take time to master it, the SnS is very much OP'd compared to most other blademaster weapons. I also recently mastered and learned the back-jump SnS charge attack, which is a very good move when fighting monsters who like to flail around, or is otherwise difficult to chain combos on upclose. If done right you can get atleast two hits in one go, with one of the hits being a stun attack. (seriously, why is this weapon not more popular?)
Anyways, as I mentioned, I am currently learning to use the Longsword. For the longer weapons I think it will be my go-to weapon. The Charge Blade is extremely good, but takes so long to set up the more powerful attacks! the longsword you can atleast chain into attacks to get the spirit gage up, and can get very quick attacks with, which i was surprised with.
However, I doubt I'll be using any of the larger weapons against the quicker monsters, or even when Soloing (on purpose). I like my speed too much with Dual Blades and SnS, plus my style is too much leaning towards DB & SnS to ever gain the same level of mastery with a larger, slower, more precise oriented weapon. I'll still be using them, but not for any serious missions.
