All these things could go with a storyline, and the way ill have the quests, one quest will go on to the next.

so a quest like go kill 10 bats, will then go on to one like Use the bat wings to make a magic dagger
and so on.

Making a magic dagger from bat wings doesn't seem like much of a quest.   The term "quest" usually suggests some kind of long journey/search.  And it usually involves an epic or heroic effort by the character.  What you're describing seems more like a "task".

Not that it matters much to your game.  It's just semantics.

that bat and dagger thing was just a example, some of the quests might be simular, like to kill snakes, until you get enough snake fangs to make a magic staff, that you use to kill a god, which will become destroyed after the quest.

Its a mmorpg, the style will be a bit cartoonish, and will take place around 1200AD
theres spells, monsters, and also will be dungeons.

Well there goes my idea about intrigue and deception in the Papacy! Cartoonish style is quite hard to reconcile with the events of AD 1200, where everything was life was short, brutal and unpleasant. I mean, you couldn't do the Crusades in a cartoon style - nor the French Wars of Religion. So you're left with a kind of Ye Olde Mediaeval world that doesn't really fit into any specific time.

As for a grand quest arc: how about helping to secure your master as the Holy Roman Emperor? Or trying to help your master unite the Italian states under one ruler (think Machiavelli)? That way you have a whole variety of smaller quests: assassinate someone; bring such-and-such relic to so-and-so; help him; kill him; etc.

well with the way it is, there isnt much for religion, emperors, or anything like that.
and we might not kill people, maybe just monsters and gods. the people npc's will mostly be stores, and magic trainers.

well, me and my friend choose different cultures for weapons and armor. even gave them names like cuirass, pauldrons, greaves. and since it takes place during the 1200's, it will also have some castles.

All these things could go with a storyline, and the way ill have the quests, one quest will go on to the next.

so a quest like go kill 10 bats, will then go on to one like Use the bat wings to make a magic dagger
and so on.

Well i think the most important part of a game is the gameplay, and see if it has a good story.

Maybe sound and music would be nice?

You said you wanted to check if another user has gm pro?
There is a function that checks if your version if gm pro

gamemaker_pro Indicates whether the game is created with the Pro Edition.

But i don't think there is anything that could check if another user does.
