I has:
- a slim PS2 with 70+ games (yah dis a gewd system)(I bought a lot of games used)
- a model-1 PS2 now stuck in a drawer due to a weak laser
- a Dreamcast with roughly a dozen games (I only gots the best ones) (+ some pirated and emus and roms)
- a Gamecube with about 20 games (including both Zelda special collector's discs)
- a 360 with about seven games
- an XBOX with about 20 games (+ emus and roms)
- a DS with about a dozen titles
- a GBA SP+ with about 20 games (not including all my GB and GBC ones)
- a PSP with 4 games (+ some ISOs, and emus and roms)
- a Wii with about 10 games (+ VC and Wii Ware).
- an SNES with about a dozen games
- a Genesis with about a dozen games
- a Color Gameboy I haven't used in ages, and also an original "green-screen" Gameboy that met it's fate in a flea dip and that I display as part of a VG srine now)
- an original GBA, modified with a front light that probably has as many dust mites as it does smudges on its LCD (see I tried opening it up and wiping it down with a moist cloth ---- NEVER AGAIN will I treat an LCD this way)
- a Saturn I borrowed from my brother to play Panzer Dragoon Saga and which he never asked for back. I also played NitM with this off of a burned copy.
- an N64 with about 15 games (upgraded with expansion pack and a still-working rumble pack)
- a broken original model PSX that is now a part of my VG shrine on my bookcase.
....in conclusion: that's why Castlevania is inconsistent.
