You can spend 100M upgrading brickout for a lousy 2.3K DPS. This is a very strange game, where most of the upgrades / boards are totally useless. Even in the one that pays off the most, lawn mowing, only the top two upgrades are worth anything.
Yeah no I'm not going to spend hours and hours grinding for viscera. You gotta fix that. Have those damn bugs show up on radar or have them drop 20, not 2.
