As the title suggests I am looking for some good animes (or perhaps in dire need of something new) so if you could please recommend some good animes  

Depends on the genre, what are looking for?  

Can you let us know about what animes you've already seen so we don't just pointlessly throw titles that you've already seen at you?  

As the other has mentioned, you should really give your preference in anime.  

Well as far as genre's I like magical girl, adventure, fantasy, humor

Animees I have seen

bleach
pokemon
Yu-gi-oh
sailor moon
tokyo mew mew
pretty cure (I think that's what its called)
shugo chara
shugo chara doki
shugo chara doki doki
shugo chara party
one piece
attack on titan
fairy tail
space dandy
pudella madoka magica
Ao no blue exorcist
death note
fullmetal alchemist
alta no prince sama
Inuyasha
naruto
flame of recca
Ohshc  

You like action, rightly then try Hunter x Hunter 2011, this version is better.
A great and exciting anime that's currently ongoing.  

Based on what you've seen, tons of those anime are focused for/popular in the west. Well seeing how you watch tons of those shonen, can't say you'll really like Hunter x Hunter since it is not mainly a fighting, but it's amazing for it's character and story writing, heck the last episode was pretty much a group of guys standing in one spot the whole episode, but the dialouges between the characters are what made it such an intense episode.

A series similar to Yu-Gi-Oh is Cardfight Vangaurd (I only know about this since a bunch of my friends plays the card game and is a big strategic and luck based game)

The currently airing and most standout of this season is No Game No Life, has tons of humor, serious strategic moments and amazing art style.

Fate/kaleid liner Prisma☆Illya is a magical girl series that is a spin off from the Fate Project (Highly recommend to watch Fate/Zero aswell, but it's a more mature series). I've only seen the first episode, but it's getting a second season, so it must be pretty good in Japan.

Now for more Hunter x Hunter discussion:
Hunter x Hunter is not like your regular shonen series. It has a more complex fighting system then the typical, "oh I trained for a few days and got super power will no backfire to completely destro... damn this enemy has an even more OP power than me." The most popular arc is it's current one called the Chimera Ant, which has a potential of being a seinen series instead of Shonen. What makes the Chimera Ant so unique is it's character development and the story writing itself is pure gold. Hunter x Hunter is rated in the top 15 anime in MAL for a reason.

Not gonna go into detail plots and stuff but :

Soul eater <~ fantasy fights, unique plot , it's a bit slow on it's introduction but gets really good after it's done through that stage

D.greyman
Similar to blue exorsist where the main character goes to a school type of place to learn and improve his powers bla bla bla


Magi
2 season anime
Unique plot
Very interesting + mysterious story
Fun adventure
Fantasy/magic XD
probably one of my favourites.
