My shop has a Fortress and one other player has another and neither see play outside of 10k+ Apocalypse games. They're nice centerpieces but they are HARD to play around. If you want it as a terrain piece, sure, go for it. There's not many normal games that can even play around it. Large bases like Tyranids, Daemons, Knights of all types, they all struggle on the terrain. It's got a lot sharp bits that will take damage if you set the model on top.
