Do any of you guys know any lightweight interesting games for a somewhat weak laptop like mine?

Alright, so I'm kind of bored right now and i just want to have fun using my laptop. Here is what i see on the "Properties" when i right-click "Computer" in the start menu:
Windows 7
Processor: AMD C-50 Processor 1.00GHz
Installed Memory (RAM): 2.00 GB
System Type: 64-bit Operating system
no Pen or Touch input is available

I don't know much but I commonly base a game if i can run it by the Processor (particularly the 1.00GHz) and checked the minimum processor required to run Minecraft which stated Pentium 4 1.6 GHz which tells me that "AMD C-50 is more powerful than Pentium 4 so yeah. With that thing in my mind, I searched for other games to play that i can run properly but i haven't seen any other games. What I can play now are: Half-Minute Hero, Amnesia: the Dark Descent, Garrys Mod (sometimes get's laggy), Warcraft III Frozen Throne, Starcraft (only, I'm 100% sure i can't run SC 2), Hearthstones: Heroes of Warcraft, Diablo: Hellfire, Who's That Flying?! And World Of Goo. Are there any other games that I might like? Actually, no, please list all games that you are sure that i can run.

I'm sure that you can run and reasonably enjoy the following games

Age of Empires 1 and 1.2
Rise of Nations
midtown madness
FLASH games (be sure to get them from trustworthy sources)plenty
