I’ve mentioned in a previous article that XCOM: Enemy Unknown’s basic mechanics are, with a few exceptions, easily transferable to the tabletop and would be a significant improvement over D&D mechanics for just about any edition you care to name. Today I’m going to talk about something else tabletop RPGs can learn from XCOM, although this time it’s going to be less of something where you can copy and paste the existing XCOM material in with only minimal changes and more something where a general design philosophy should be learned from, even though the specific implementation cannot reasonably be copied. Today, I’m going to talk about NPCs.
In XC:EU there is a steadily escalating stock of enemy aliens, with new aliens introduced each month. XCOM also gets new funding each month depending on performance so far, and research into alien technology to be replicated and construction of new facilities also takes time (and money, the accumulation of which takes time), so there is a constant arms race between XCOM and the aliens. Here we already see how the direct analogue to D&D breaks down. You could set up a specific campaign whose premise was an XCOM style arms race where the party is under pressure to level or gear up in response to escalating monster threat (I might actually do that sometime), but that’s a specific campaign premise, not something you can generalize to all of D&D.
That said, the way in which aliens become steadily more deadly as time goes on does map to NPCs getting stronger as level goes up. Rather than an arms race where players must level their characters fast enough to keep up with the NPCs, in most D&D games either the NPCs automatically level to match the players or else their levels are static and the players are expected to seek out encounters appropriate to their level.
What can and should be learned from XC:EU’s enemy design is the way the game changes as the power level goes up. As an example, let’s look at a series of three enemies, all from the base game, the sectoid, the muton, and the sectopod. These three enemies are your main bruiser enemy at tiers one, two, and three of the game respectively. You fight sectoids at the very beginning with regular body armor and mundane assault rifles, you fight mutons with carapace armor and laser rifles, and you fight sectopods with titan armor and plasma rifles. Or maybe you fall behind the gear curve and get murdered horribly. What’s important is that, although the sectoid has three health, the muton has eight, and the sectopod has a staggering twenty-five, that is not the beginning and the end of the differences between them.
