This is true with basically everything. Game development attracts more than its fair share of truly horrid code, to the point where success seems almost inversely correlated to code quality. If you decompile Terraria (using CIL, which preserves the object design), for instance, you'll notice that its main class is over 40kLOC and that basically all of the business logic is encoded in one great big chain of if-statements. However, the game has been extremely popular and successful (and is pretty fast, and looks really pretty).
Somewhere there is a balance, but for business purposes it leans closer to the "working ugly hack" side.
