I am an off the cuff GM (4e), I make it up as I go and draw quick and dirty maps on the spot. One thing I like about Roll20 is I can just keep adding onto a map as needed. But there is a drawback, to stay fast I have to limit my terrain to just like in a forest, generic splotches of difficult terrain and trees. And I was wondering how useful tiles are? Like with forest tiles, can I just keep adding tiles indefinitely and how fast is it to do so? I was looking at the three quick encounter packs and generic forest and thats a $21 purchase which is pretty hefty for something I'm not sure will be useful. And looking at the tiles offered I wasn't sold that it could accomplish this. If I'm not making myself clear just say so. I'm pretty sure for it to work I'll need completely predecorated tiles that I can just fit together into larger and larger maps. And although they have tiles that look like they could work, the problem is they all seem to have objects that run off the edges. Now I'm not sure thats a deal breaker or not, which is why I'm asking for advice. Would the players notice? Would they care? I already sank a huge chunk of money into a year's subscription of mentor so I really need to make sure I don't waste money on this. But if premade tiles could work well and fast (or faster) then I think that would be a great addition to my game. But I don't know. And I panic when it comes to money.
