Fans are thrilled with the incredible character selection and nostalgic details packed into Mulder's office, though some note the diorama format leaves less room for expansive building.

📝 Our Take

The X-Files (21369) is the ultimate 90s nostalgia trip for sci-fi fans and LEGO collectors alike. Winning the LEGO Ideas '90s Nostalgia Challenge, this set brilliantly captures the eerie, paranoid aesthetic of the iconic television series with a dual-focus model featuring Mulder's office and a classic UFO encounter.

This set is perfect for dedicated fans of the paranormal and adult collectors looking for a striking display piece. With 1,478 pieces and 8 minifigures including Mulder, Scully, and the Cigarette Smoking Man, it offers an engaging build experience that packs plenty of Easter eggs into a compact footprint.

Skip this if you have no attachment to the source material or prefer sleek sci-fi vehicles. While packed with character, the office diorama format might not appeal to general builders who aren't chasing that specific X-Files vibe.

📈 Investment Analysis

↑ Trending up since release

A-

Investment Grade

Current release

As a winning entry from the LEGO Ideas platform based on a massive cult-classic television franchise, The X-Files (21369) holds fantastic investment potential. Licensed TV show sets with dedicated adult fan bases traditionally perform very well on the aftermarket once they retire, especially when they include a comprehensive lineup of main characters. Given the niche 90s nostalgia appeal, supply may not reach the levels of broader mainstream themes, pointing toward healthy appreciation after retirement.
