"you have to design your areas accordingly or they will bunch up/be rendered useless at various pinch points. I avoid entrances that are a single tile wide in a building entrance, and you have to avoid combats right inside a door way as there is a good chance your ranged companions will go in first, and then be stuck because the rest rush in behind them, unable to reach with their weapons but still blocking the doorway. Two tile rule for any combats for the most part, or stick to outdoors."
Well, for the life of me I had not thought about it! And I had better do it, since LoL will feature 4 companions. Don't want them to mess up with one another with the caster ending up in front surrounded by foes and the tank stuck at the back of the group without any possibility to move!
Anyway, reading the above made me think and - after a toast to my noobishness - I went and remade the area I am currently working on, a few WIP pics of which are shown herein below. It is supposedly a ugly spot in the Nether Mountains where many baddies dwell. And the PC's got to clean it up! how innovative... please be impressed! Basically I had to make the paths larger because there was no way a party could walk them without jamming. Now it is still narrow but I am confident that at least they will be able to move, albeit cumbersomely.
Of course, if and when LoL is finished this post will be deleted and I will claim that my mountain areas where thoroughly thought out and cleverly designed in order to provide players with a realistic and immersive feeling of barren and inhospitable lands that could also force them to think strategically in order to implement the best tactics to take care of the above-mentioned baddies in their own environment!
