Re: FPGA game console
This game can be implemented on xilinx fpga using VHDL or Verilog language only. C or c++ language in fpga is used for programming soft core processor (Microblaze) soft core Microcontroller (picoblaze) and also for hardcore processor (like powerPC). I made a ping pong game on xilinx spartan series fpga using vhdl language. It is possible that you may require external memory (sd card, etc) for increasing the graphics quality of your game while all the controllers(vga controller, sd card reader controller, etc) can be implemented on fpga.

you should read 11 and 12 chapters of this book for interfacing monitor with fpga:
