The game isn't perfect, of course. We can't wait to try Giants in multiplayer mode, but we'll have to wait; according to MacPlay, a patch is under development. Also, like a growing number of today's games, it lacks an in-mission save. That's OK in some of the shorter missions. If you goof up, it's easy enough to play through again. But when missions get longer, dying inches short of the final goal is maddening. The game's strenuous requirements may frustrate you as well: The stated system requirements are definitely minimum requirements, and Giants is built exclusively for Mac OS X. But hey, maybe that's a plus. If you've been putting off upgrading, start digging for your wallet. Giants may be your best excuse yet.
