I bought a delica about 2 months ago. It's been one of my edc's but I've only cut 2 or 3 things with it, soft materials. Ocasionally I'll play with it and open it up and close it. There is now blade play when the knife is open and locked in both directions. It is still locking up solid, the blade play isnt much, but it's the most I've seen in any of my folders. Actually, none of my other folders have blade play, even after abusing my ti lite for 2 years. Is this normal? I cant find any other threads on this.

Cover the knife with a cloth, and 'gently' hammer on the pivot pin, and check for play. Too much and it'll be too tight.
I had an Atlatic Salt with very much blade play. I hammered the pivot to the point you couldn't open it one handedly anymore. Then I dripped some oil in the pivot, put the blow dryer to the pivot for 5 minutes, let it cool, work the knife, put the blow dryer to the pivot for another 10 minutes and let it cool after that. Then the knife was ok ( stiffer than it was but I could open it with one hand) I moved the blade forcefully in both directions but there wasn't a fraction of blade play anymore.

Side-to-side or up-down play?
A tad of up-down play isn't uncommon in lockbacks. As long as it isn't closing on you (try some spine-whacks to be sure), don't worry about it.
If it's side-to-side play, and it's getting excessive, I'd send it in to be looked at. Most any FRN handled Spyderco will have a bit of side-to-side flex. Part of it's because it's rivoted, and not held by an adjustable screw, and part of it's because the FRN itself can flex. With any of my FRN Spydies, I can flex the blade to one side enough to slip a piece of paper in the gap. No big deal. If you can, say, stick a piece of cardboard in the gap, that's too much.
