Organizers have announced several notable new talks for next month's Independent Games Summit at GDC Europe in Cologne, including creating the text-based hit, Steve Jackson's Sorcery!; building the Indie Megabooth's presence at PAX and in the press; and porting Canabalt and Super Crate Box to the Commodore 64 - also revealing a new extra with the reduced-price Indie Games Summit Pass.

These talks are part of GDC Europe 2013's Independent Games Summit (IGS), a sister event to the IGS which takes place during the IGF. GDC Europe's IGS will be held Tuesday, August 20th, during the three-day conference at Cologne Congress-Centrum Ost in Cologne, Germany - just ahead of (and co-located with) the massive 275,000 person Gamescom event.

These likely to be popular talks are accessible via the reduced-price Independent Games Summit pass for the show, but are also available for all GDC Europe passholders.

Organizers are also announcing that the Indie Games Summit Pass will now include a two-day pass to the Gamescom event itself, including attendance during the business day on Wednesday, August 21st - a significant additional perk.

The breakdown of the newly added talks, part of an extensive line-up for the day, are as follows:
