I have noticed that some people ask for RTP sprites and others ask for isometric sprites. I am new to rpg maker and was wondering if someone could better explain what all this means. Like give me a pros and cons type deal so i can better understand and evaluate what is better for me too use. Thank you for your time. Also i am using RMVX.

The RTP - "run time package" - is the collection of sprites and other resources that come with RPG Maker VX. They are drawn in a top-down perspective, a la every Final Fantasy game before Cloud Strife came into the picture.

Isometric sprites are drawn from a different perspective than the RTP sprites. Of course, there are plenty of non-RTP sprites that are not isometric, but that's not really important.

In general, you will want to use top-down sprites at this point because you would have to find a script (or find somebody who could write a script) that would allow you to use isometric sprites and tilesets (er, maps) in your game, a hassle that would not really do much to improve the graphics of your game in the first place.
However, since the RTP is naturally overused (and given your position as an artist), I'd advise you to edit RTP sprites (recolor/put someone's head over someone else's body) or make your own. I know that there are plenty of tutorials on RRR and in other places concerning spriting, so those should help you if you decide to do some artwork.
If you can't be bothered to do that, then there are plenty of free resources available online for sprites, windowskins, etc.

thanks for the advise and ill look into to it. Was wanting to make a game using Final Fantasy Tactics sprites so this helped out a alot. Is there anything special i would need to deal with when it comes to working with Final Fantasy tactics sprites? Any advice?
