PSIXX'S PROFILE

I have a couple of questions that need to be answered.

1. Is there any way to use an item/skill ingame while NOT in battle? Of course, using a skill ingame (like healing) may break up the balance, but everyne's games are different so if there's a disbalance, there are many ways to fix it.

2. I'm making a story and a class that needs skills to require items. Is it possible to use a skill that requires items to make ANOTHER item? Or, at least, without making another item.

3. What version of the RPG maker is the best? Which has more freedom and mods(if there are any) available for download? Also, im not very satisfied with the graphics in VX. I'd like something with a nostalgic, older feeling.

Thank you.
