CREEDMOOR â A donation from one of the co-founders of one of the worldâs wealthiest video-game companies has enabled the Tar River Land Conservatory to increase the size of a nature preserve near Creedmoor by more than 50%. Conservancy officials announced recently that their organization had received 83 acres in the Swift Creek area and âa significant financial contributionâ from Mark and Tara Rein. Mark Rein is co-founder and vice president of Epic Games, the Cary software house that makes and publishes Fortnite, the gaming sensation whose success over the past few years has helped push the companyâs value to almost $29 billion.
