The new pacing is much more reasonable. There's a bit of late game difficulty with it, but it's still substantially better.
In the "late game", once the player has access to the strongest drill, process slows to a crawl. Shutting the game down and leaving it alone for a while (say, long enough to cap out the eight hours) means coming back to either a completed game or one where the player has so much money they can bulk up on high end equipment, then take another break and win while away.
