@MskoDestny,
If you're considering a simple 68k based system, have a look at the
MC68306, 20Mhz 68000 core with 2 timers, 1 uart, DRAM controller,interrupt controller ,programmable external chip selects etc, the only downside for hobbyist use is the QFP package.
Now if someone can come up with a simple 24bit gfx chipset that can do TV output and needs a minimum of glue logic to interface to the 68k, then I have a cunning idea..
