I've noticed the last few days that MyPlayCity has been offering new games more frequently and a lot of them seem to be old Alawar games.
Now check out the batter at the MyPlayCity site! They're offering a new game every day this month!
You do have to watch for toolbar/homepage/search engine changes/additions but their minor. They have stopped the "stub" install that then download and installs the game and they don't seem as push on the toolbar.
If you have the Ask Toolbar for any other reason (such as Avira Personal's WebGuard), it's a non-issue. Even if you have to install it, you can simply disable it. MPC doesn't care if you USE the toolbar, they just want you to have it and even then, I'm not sure it's installing.
Typical opening of the browser when the game ends but that's minor for free, non-ad-supported games.
Just keep an eye on them. I'll be busy keeping my "Free Games" spreadsheet up to date this month. I track MyPlayCity, FreeGamePick, GameTop and Jenkat.
If you miss a game the first day, don't worry. It will STAY there as far as I know with all their other games!
