Portal's biggest title for Spiel 2015 was undoubtedly the second edition of Ignacy Trzewiczek's Stronghold, published in cooperation with Stronghold Games.
• The other reboot from Portal Games was Neuroshima: Convoy, which retains the head-to-head Moloch vs. Outpost nature of the original 2012 release while also streamlining play through the elimination of the special abilities on individual city boards.
• Legacy: The Testament of Duke de Crecy – Five Families is a long title that already gives you a taste of what's included in this expansion for Michiel Hendriks' family-building game Legacy. Ideally for 2016 Portal Games will partner with Rob Daviau on a second expansion to be released under the name "Legacy Legacy".
• Theseus: The Dark Orbit – Hunters adds a new faction to this "locked room" battle in space from Michał Oracz, with the hunters being the only faction able to unlock that room and step outside for a little while.
• In case you missed those earlier three releases from Portal at Gen Con 2015 — Tides of Time, Imperial Settlers: Atlanteans and Rattle, Battle, Grab the Loot — Trzewiczek gives an overview of the trio at Spiel 2015.
