I'm feeling really naive about this subject and so I figured I would see if you guys could help me.

I'm wanting to create a style of game that features a grid like system much like Sim City, in which there are hundreds of cells in two directions. The game engine I'm currently using is Unity3D, but it really shouldn't have much of an impact.

The way I figured this would be done is to generate these millions of objects in a nested loop, and having a hash table to store references to the objects. The objects would then have to be batched together into larger meshes for rendering so that you're not dealing with millions of draw calls.

The problem I see is how can I take these large combined meshes and figure out which particular cell my raycast hits when I click on a piece of geometry, so I can change the model out, etc, and then recombine the mesh once I'm finished. The other problem I see is... is it inherently bad to have every single cell loaded into memory? That seems like it would be a huge consumer of memory.

How am I thinking about this wrong? So many older games like sim city and diablo and stuff use grid like systems that contain all sorts of information... but how do they do it efficiently?

Please help me feel less stupid!

      The Emotional Music Vol. I pack focuses on beautiful and esoteric orchestral music, capable of creating truly emotive and intimate moods. It features detailed chamber strings, cello and piano as the main instruments, resulting in a subtle and elegant sound never before heard in video game royalty-free music assets.

      The pack includes 5 original tracks, as well as a total of 47 loops based on these tracks (long loops for simple use and short loops for custom / complex music layering).

What this means is that players can choose to play as the people invading the dungeon, or as the dungeon-holders themselves.

      -Intense, fast-paced combat
      -Multiple skills, weapons, and ways to play the game
