Table Games - Tacky??

So I was recently at the beautiful wedding of our friends Beth and Shawn, there wedding was wonderful and they had this neat little "game" of ISpy. On each table they had a disposable camera and a little iSpy list of things to take pictures of, I thought it was a really cute and creative idea and it helped to start conversation amongst our table.
I know as adults we should be able to carry on conversations, but sometimes when you're thrown in the mix with people you don't normally converse with, sometimes you need something to get the conversation started... which brings me to what I'm thinking for a table "game"

I have got two ideas, now I've heard it's tacky to do table games... so feedback on this would be very appreciated!!

At each table we would have a 8x10 picture of Brian and I, some would be goofy, some serious, whatever... and then there would be a little "thought-bubble" note card for each guest to fill out during dinner, sort of like a "caption-this" type thing...
so each person (optional for people to participate) would fill out their best caption for the photo... the DJ would come around while people are eating and go through and read out the captions, the "winner" at each table would get a small prize...
I figured it would be a good way to keep peoples attention during dinner and create a fun atmosphere... get some people laughing, etc.

Another idea I got from a website I was browsing... at each seat there would be an envelope containing the name of another person at the wedding, the object of the game is to find that person and draw a portrait of them on the back of the card... this game is meant to get people to mingle with one another... at the end of the reception each guest puts their self-drawn photo in a basket to "earn their favor"

I definitely like the first idea the best, but should I do with out any?
On the flip sides, I've read that table games are tacky and should only be played during the bridal shower?
Thoughts on this...
