C&C4 Was ich nicht ganz verstehe....

Sie vergleichen es mit (MMO)RPGs, also ja.

First, we have the persistent player profile; with every unit you kill, you'll earn experience you can put toward upgrading your class and progressing through the game.

SB: Essentially, whenever you play Command & Conquer 4, be it in single-player, co-op, skirmish, or online, you earn experience that collects in your persistent player profile. Within the profile, you use your experience pool to level up your classes, earning new units, structures, powers, and upgrades. Since your profile is persistent across the game, you can then take your new toys and put them to use in any of our game modes.

Also jede zerstörte Einheit bringt Erfahrungspunkte, die man zum Upgrade der drei Klassen nutzen kann und so neue Sachen freischaltet. Das ganze wird in einem dauerhaften Spielerprofil gesichert, weshalb man auch für Singleplayer online sein muss.
