One thing that I feel like Arena Rex might benefit from is a supplement that deals with options to use what I here call "alternative arena design". By this I mean some kind of arena that isn't a standard arena, i.e. flat and open, with some hazards scattered around it.
As it is now, the game is designed to be played in a standard arena, and it works really well. It's perfectly cool to just leave it at that. It does make sense. The point of the arena being flat and open is that it is really easy for the spectators to look down and see all the action.
But I kinda like thinking in options and alternatives for default settings, especially when it comes to something visual.
One simple example is: How about some kind of labyrinth? I.e. instead of a big open space, you would have a bunch of interconnected corridors and passages.
If you made an arena like that, would it make sense to consider every wall to be a hazard? Then hazards would be everywhere, and basically every attack would easily be able to push the opponent into a wall (since just touching the wall at an angle would suffice). Would that be fun, or boring? Plus, there are no rules for line of sight in the core game, so in principle models would be able to attack each other through walls if the walls were thin, unless you made a house rule to change that.
Another possibility is to have elevated levels in the arena, like platforms that would require steps or ladders to get on or off. This is something that there are no rules for at all in the core rules, so players would have to make these up - which is something I'm considering doing just now. Hence this thread.
Any thoughts welcome.
