Yes, there are reports of shortages and yes, we know that it's not the fully branded PlayStation phone that the rumour mill has talked about for years - but the Sony Ericsson Xperia Play is still a big deal and it has just gone on sale in the UK.

And, for a mobile phone with gaming at its heart your first question is bound to be: "What games can I play on it?"

Well, luckily Sony Ericsson has detailed the launch range and it's a mix of original PlayStation games, existing "3D titles" and "popular casual games all optimized for the unique game pad". The phone giant has also stated that there are 20 developers on board "from big publishers to independents, from middleware providers Havok and Unity to engaging Android developers".
