Here are some that I would recommend for games with Spelljammer type of setting: Sky Ships -- essential and on-point, this could cover most of your ship needs for a full campaign, <a href="https://marketplace.roll20.net/browse/set/1863/tra" rel="nofollow">https://marketplace.roll20.net/browse/set/1863/tra</a>... Alien Worlds -- surfaces, battle maps on different worlds to land on, this would be for up-close and yet plenty of elbow-room for long range, <a href="https://marketplace.roll20.net/browse/set/583/alie" rel="nofollow">https://marketplace.roll20.net/browse/set/583/alie</a>... Planets and planetary system maps, and space backgrounds, take your pick or mix & match from these: <a href="https://marketplace.roll20.net/browse/set/1306/spa" rel="nofollow">https://marketplace.roll20.net/browse/set/1306/spa</a>... <a href="https://marketplace.roll20.net/browse/set/1310/spa" rel="nofollow">https://marketplace.roll20.net/browse/set/1310/spa</a>... <a href="https://marketplace.roll20.net/browse/set/72/wrigh" rel="nofollow">https://marketplace.roll20.net/browse/set/72/wrigh</a>... <a href="https://marketplace.roll20.net/browse/set/550/vile" rel="nofollow">https://marketplace.roll20.net/browse/set/550/vile</a>... I've not included any monsters or token suggestions here, though. Many (any) from traditional fantasy D&D art packs, can work in SJ. The thread is open for more feedback from the community.
