IGN has reached to Activision about clarification on the content download for the Spyro Reignited Trilogy that stated to need the internet in order to download Spyro 2 and 3.
IGN wrote:
"Activision has confirmed to IGN that "The trilogy will ship with content from each of the three games, including the entire first game and a subset of levels from games 2 and 3. In order for the full Reignited Trilogy offerings, a day one update is required.
When asked for further clarification, Activision confirmed this means some full levels will be included on the Reignited Trilogy disc, and other full levels will need to be downloaded as part of a Day 1 update. So, should someone purchase the Trilogy on disc but not be able to connect their console to the internet, they would be able to play those levels on the disc, but not the full, original level suites of Spyro: Ripto's Rage and Spyro: Year of the Dragon.""
