Walkthroughs: Command and Conquer 4 Tiberian Twilight Walkthrough Command and Conquer 4 Tiberian Twilight Game Guide
Which is entirely not the case in Command & Conquer 4, largely thanks (or not) to a new me-too persistent unlock system. Persistent unlocks are great in some contexts, but not in a way which means people starting out only have access to three different units and pretty much zero Support powers.
The careful unit-balancing means it is possible to take down a flock of tanks with a swarm of tier-1 infantry, which is an admirable achievement from a series traditionally known for races up the tech tree. But it would be much easier, and much more fun, to use tier-2 Mammoths and Scorpion Tanks, or tier-3 Support powers that blow up half the screen, which you cant do for too long.
