Hack Slash Crawl is a brilliant isometric rogue like game.
Stwalt is a nice role-play game, “diced”.
There are others Rogue like flashgames to try…
Also this (seems) good RPG:
King’s Island (3 episodes)
Mardek (3 chapters)
and much more.. too many to list them all..
Have a nice cup of tea or a coffee break.
