Acclaim's David Perry was waiting until E3 rolled around but the news of OnLive at this week's GDC has amped up the pressure.
The project doesn't have anything to do with Acclaim, Perry is handling it himself with some Dutch engineers and hopes for investment soon. It too allows server-based user gameplay.
"I was going to reveal it at" at this year's E3 claims David Perry, "but the OnLive news has forced my hand."
His service would allow gamers to play without any need to download anything to a client machine, whereas OnLive needs to install just around one megabyte. Much like his rival though he'll need to work closely with ISPs to improve efficiency of delivery.
OnLive has little to fear from Perry just yet, but who knows what schemes those Dutchman have planned for our Internet?
