Compared to C&C: Renegade (which I enjoyed), X-Com: Enforcer is really much, much worse. Aside from yet another excuse plot and the aliens who are barely looking like themselves (mini-Reapers, everyone?), it becomes boring very quick. The gameplay itself is very repetitive and dull and even "briefings" are almost the same. However I managed to find a explaination for this - what if we will see Enforcer as in-universe video game (or rather arcade game) based on the events of First Alien War? This theory can explain why this game is so boring (video game industry in X-Com timeline isn't that advanced as IRL), hilarious (it was made a long after the first invasion) and bears almost no connection to the main series (because it's just the in-universe coin-powered arcade game).
