With the removal of the Save function in Freeplay Mode (it used to exist there), Round 500 would be extremely laggy. Spike Storm is good, but the lag associated with it would be unbearable.

Even if you had a super computer capable of handling it, I doubt Spike Storm spam would be enough to deal with blimps that gain speed and health each Round. That's why you also need Temples.
