I had some questions before, and I have now answered them.

• Do I need to travel to the future after destroying the machine in the past, or is it sufficient to just explode the generator? No, you don’t need to travel to the future; you can finish the act in the past, and you’re still told you created a good future. However, if you can travel to the future (through two future lampposts in sequence) there are no enemies in the way of you getting to the end.
• Do I need to create good futures for both acts, and if so do I then have to fight the boss? Yes, you have to create good futures for both acts, and if you do then the third act takes place in the good future – but you still have to fight the boss.

I know this, because I have spent quite some time exploring levels and working out where to time travel, where the robot generators are, and planning routes to get there; I’ve now managed it on the first five Zones, and have at least located the generator in the present on Stardust Speedway Act 1 (though I have no idea how to get to it, and this is a rare example of a 16-bit Sonic level being pretty poorly designed). Luckily I’ve built up a stock of about 25 lives, and it’s fairly easy to collect 100 rings to gain another, since I keep running out of time when exploring.

I have often thought of Sonic CD as intimidating, because I thought you needed to get everything perfect. Back in 2011 I threw caution to the wind, and played through the game on the Xbox 360, not trying for the good ending but just hoping to get to the end. It was relatively easy to do that, though levels were sometimes a bit disorderly and prevented a fluid run throughout. The race with Metal Sonic was particularly difficult.

Having plugged in my PS3 (because I wanted to test a copy of Crashed that I found), I saw Sonic CD on the list of installed games, and immediately got the sense of being overwhelmed again, because having completed the bad ending I felt I would need to try for the good one. Back in the 1990s I had time to devote to a game, and to this day I have a complete picture of all levels from Sonic 1 and 2 in my mind, crowding out information which might actually be useful. That came from playing the games over and over; by the time I got my Mega CD from Pink Planet in Bristol, I had many other things to be doing.

But in recent months I find myself wanting to spend time dedicated to specific games again, hence returning to Mario Odyssey, playing through GTA3 and Vice City, and progressing through Wreckfest. Taking time to appreciate a game in its entirety – exactly what has been holding me back from Sonic CD.

So I’ve been taking my time, exploring levels, working out routes to take, where to find time travel posts and then build up speed, trying to find the machines in the past. It’s been a very different experience, very unlike other Sonic games, but it’s been very enjoyable. I fear I may need to resort to looking at some level maps, though, if I don’t work out how to destroy the generator on Stardust Speedway soon.

Oh, and the special stages are still pretty rubbish.
