"i39 was a resounding success with hundreds of people bringing their own PCs for four days of hardcore gaming and over 2,000 turning up to take part in competitions or watch the action," says MD of Multiplay Craig Fletcher.
"Since the event, sales of tickets for i40, our summer tournament, have shot through the roof and it's now on track to break all records previously set by our 'I' series of events."
