Honored Contributor"Individual chips that can be placed on a breadboard" (meaning DIP form factor most likely) is no longer realistic. FPGAs/CPLDs (modern parts) are invariably SMT packaging.
That being said, there are solutions for this, being mini development boards that are setup in a DIP form factor, suitable for plugging into breadboards. Digilent makes a number of them in their CMOD series: https://store.digilentinc.com/search.php?search=&search_query=cmod They range from lower end CPLDs for basic logic, to a mid size (Spartan) and a higher end (Artix) FPGA part. Sadly I don't know of any vendor that produces equivalent types of boards that use Altera parts (Digilent boards are Xilinx based, just like TerAsic boards are Altera based). No technical reason you could not, just no vendor support. Maybe someone else knows of similar types of pluggable boards with Altera parts.
