Sony Computer Entertainment CEO Andrew House has admitted the PS4's line-up of first-party games in 2015 is "a little sparse", while speaking at the Electronics segment of the company's Investor Relations Day.

This is largely down to Naughty Dog's Uncharted 4: A Thief's End being delayed until 2016, but House stated the game was still "critical" to Sony's 2015 fiscal year, meaning it is likely to be released before 31 March 2016 when the financial year closes.

Third parties will help ease the pressure felt by the absence of Uncharted, which has left the company with very few games for release in 2015. Until Dawn, Tearaway Unfolded and God Of War III Remastered are the only games of note, with No Man's Sky expected by some but no release date has been confirmed yet. More games are expected to be revealed at E3 in June.

According to DualShockers, House said Sony is working "very hard" to support the raft of third-party publishers and developers who support PlayStation consoles, adding exclusivity deals with third parties are becoming "increasingly difficult to secure".

This came in response to a question about how confident he felt about third parties producing exclusive content for PS4, to which House said he would respond in a "constrained" manner. He first of all said ahead of any exclusivity deals, Sony is encouraging third parties to make full use of the PS4 and its features.

House also cited Destiny as an example of a third-party game for which Sony had secured some sort of deal, even if it was not outright or of timed exclusivity. He described such exclusives as "few and far between" but cited Capcom's Street Fighter 5 as a major, upcoming example.
