Tecmo's latest, The Isle of 8-Bit Treasures, is misleadingly titled. No 8-bit system was even remotely capable of producing the number of colors or the level of visual detail here present. Visually, audibly the game is more akin to games from the 16-bit era, on the SNES for example. A minor quibble, but if you're the sort that fears dated graphics and quivers at bits numbering in the single digits, fret not; The Isle of 8-Bit Treasures is prettier than the name would imply.
The game is a roguelike, in that you will spend your time exploring randomly generated dungeons, fending off the local denizens and looting as you go. As you progress deeper into a dungeon, you will face foes of increasing strength; and should you perils at their hands, you will lose all experience and treasures accumulated in the dungeon thus far. Roguelikes comprise a subgenre of role-playing games notorious for their difficulty; The Isle of 8-Bit Treasures will not hold you hand, and it will not go easy on you.
